Whereas some woodworkers want to make use of Japanese-style handsaws, which minimize on the pull stroke, others want Western-style saws, which minimize on the push. As a result of a push minimize places the blade in compression, Western saws want thicker blade plates to forestall them from buckling, and so they usually add a backbone, or sawback, to extend stiffness additional.
Their beefier construct makes Western-style saws pricier, however it additionally makes them a lot simpler to sharpen. Most woodworkers who use Japanese sawblades merely substitute them once they grow to be boring, whereas customers of Western-style “backsaws” can preserve their blades for all times.
Because of this you could find superb backsaws on the used market and restore them to their former glory. See my article in final 12 months’s Instruments & Outlets on rehabbing and sustaining a vintage-style backsaw (FWW #320), in addition to my earlier step-by-step sharpening information (Handwork, FWW #250), for every thing it’s essential know.
The recommendation in these articles holds true for each new and classic backsaws, as does my recommendation on this article on choosing the proper Western-style backsaws to your wants. I’m the founder and former proprietor of Unhealthy Axe Instrument Works, a producer of high-quality Western-style backsaws.
In that function I helped hundreds of consumers navigate the world of conventional handsaws. After retiring and promoting the corporate to its workers in 2022, I began a part-time enterprise repairing classic saws and educating saw-maintenance seminars. I’ve discovered so much about matching makers with saws.
There are fairly a couple of totally different handsaws in producers’ lineups, and the alternatives may be overwhelming. For a wide range of causes, customers are likely to go along with a devoted dovetail noticed as their first backsaw. It is a mistake, in my view. Reducing tight dovetails is a talent that comes later within the journeys of most woodworkers, after they’ve mastered a wide range of extra primary hand-tool duties.
Subsequently, most customers will derive extra worth from a bigger, extra versatile backsaw—one that may minimize dovetails and way more. That’s the carcase noticed, which stays on my bench for about 75% of my reducing necessities. After that I like to recommend a tenon noticed, and—lastly—the devoted dovetail noticed that almost all people begin out with.
1. Carcase noticed
Whether or not you purchase a brand new or classic carcase noticed, right here’s what to search for, in addition to a couple of examples of what this versatile device can do. I like to recommend hybrid sharpening, however you are able to do this your self, so the tooth don’t should be filed this option to begin.
Carcase saws can do all of it. A 14-in.-long carcase noticed, with the tooth filed “hybrid” for ripping and crosscutting, will deal with every thing from primary crosscuts to dovetails, tenons, rabbets, dadoes, and extra.

What to search for. Go for a 14-in.-long noticed with a 0.018- to 0.020-in.-thick, 13- or 14-ppi blade, filed in a hybrid sample. There are fairly plenty of new and used saws with these specs.

Good for nearly every thing. This noticed could make primary crosscuts, rip cuts, and miter cuts, and it will possibly deal with a lot of the joinery you’ll minimize, from dovetails and tenons to rabbets, dadoes, and extra.
Begin with a protracted, hybrid-filed carcase noticed
A carcase noticed is sizable sufficient to deal with giant crosscuts and large miters, but it’s refined sufficient for nice joinery cuts. It’s the workhorse of the backsaw arsenal. Hybrid-filed tooth minimize fantastically throughout the grain, and so they rip fairly effectively as nicely. To make your carcase noticed as versatile as doable, search for a longish one which has a comparatively skinny blade.
An extended noticed permits you to lengthen your reducing strokes, which can assist you to minimize straighter, and it additionally distributes put on alongside the toothline, maintaining the tooth sharper for longer. Various noticed makers—together with Unhealthy Axe, Lie-Nielsen, and some smaller operations—supply a 14-in. noticed (with the specs cited at proper)somewhat than the same old 12-in. mannequin.
2. Tenon noticed
The tenon noticed is a bigger model of the carcase noticed, with a thicker plate and barely coarser tooth, serving to it make deeper, wider cuts on bigger workpieces. For greatest outcomes on each rip cuts and crosscuts, the tooth ought to have the identical hybrid submitting sample as your carcase noticed.
Purchase a tenon noticed for greater cuts. For deeper, wider cuts on bigger workpieces—for a workbench construct, for instance—you desire a 16-or 18-in.-long tenon noticed. It makes a fantastic miter noticed too.

|
|
What to search for. Go for a 16- or 18-in.-long mannequin (these is likely to be known as sash, tenon, or miter saws) with a 0.025- to 0.032-in.- thick, 11-ppi blade, filed hybrid. New saws is likely to be filed for ripping, however you may change that once you resharpen the blade.

Deep cuts. The tenon noticed makes a speciality of deeper, longer cuts. Harrell makes use of his for reducing bigger tenons, rabbets, and dadoes, and for reducing giant miters with the assistance of his Stanley No. 150 miter field.
Purchase a big tenon noticed subsequent
That brings us to the tenon noticed, which is designed to chop deep, lengthy, correct tenons, dadoes, rabbets, and miters. There are 14-, 16-, and 18-in. choices right here, with a few of them known as carcase, sash, or miter saws. Don’t get caught up within the names.
What you’re after is a bigger noticed with a thicker plate. I like to recommend an 18-in. mannequin. It does every thing the shorter variations do but in addition cuts deeper and wider—say, for an enormous hefty mission like a workbench. I’ve used my 18-in. noticed to chop tenons as giant as 5 in. extensive and 4 in. deep.
3. Dovetail noticed
When you find yourself prepared to begin dovetailing regularly, it’s time for a devoted dovetail noticed. This noticed can be making most of its cuts consistent with the grain, so a rip-filing sample is greatest.
The dovetail noticed is a specialist. Wait to purchase a devoted dovetail noticed till you have got mastered the hand-cut dovetail and are able to assemble all your drawer containers that method.
Compact and straightforward to regulate. The thinner blade and finer pitch of a dovetail noticed work higher in thinner inventory (above) and supply glorious management when reducing half-blind dovetails (left). And the rip-filed tooth minimize extra effectively than hybrid-filed.

What to search for. Go for a 10- or 12-in.-long mannequin, with a 0.018-in.-thick, 15-ppi blade, filed for rip reducing.
When to purchase a devoted dovetail noticed
Your hybrid-filed carcase noticed will minimize dovetails in all sizes. When you have got managed to chop a number of stacks of tight dovetails along with your carcase noticed and are ready to begin dovetailing all your drawer containers by hand, you’re prepared for a devoted dovetail noticed.
I like to recommend one filed for rip cuts, as nearly all of dovetail cuts run parallel to the grain, the place rip submitting will work extra effectively than hybrid submitting. If you could find a 12-in.-long mannequin, seize it. A 0.018-in.-thick plate, filed at 15 ppi, will ship elegant pins and tails however nonetheless supply sufficient of a warmth sink to deal with lengthy dovetailing periods in inventory as thick as 5/4.
Making sense of noticed specs
Plate thickness vs. factors per inch (ppi)
All of those specs besides these within the final column are for backsaws, that are the saws used most frequently for joinery cuts. As blade plates get thicker, tooth get coarser, serving to these saws to take away sawdust and generate much less friction in deep cuts, and to dissipate the warmth these cuts produce.
Rip vs. crosscut sharpening
Saws may be sharpened (filed) for rip cuts, crosscuts, or a mixture of each (hybrid).

Rip-filed tooth
Reducing edges face ahead. This helps tooth take away materials effectively however could cause important chipout on crosscuts. Chipout isn’t an issue with rip cuts, that are consistent with the grain.
Crosscut-filed tooth
Reducing edges are angled sideways, serving to them sever fibers cleanly when reducing throughout them, decreasing chipout on again edges of cuts. However materials is eliminated comparatively slowly.
Hybrid is essentially the most versatile

Hybrid-filed tooth are angled a bit much less acutely, which helps them take away materials comparatively effectively on all sorts of cuts whereas nonetheless stopping chipout when reducing throughout the grain.
Anatomy of a backsaw
As you dive deeper into every of the three beneficial saws, it’s useful to know the fundamental traits of a Western-style handsaw and the way they contribute to the noticed’s efficiency.
As blades get thicker, the spacing of their tooth, often known as pitch and expressed as factors per inch (ppi) or tooth per inch (tpi), turns into coarser. That’s as a result of a deeper, wider minimize generates extra sawdust, and also you want bigger gullets between the tooth to hold that waste away effectively. If you happen to attempt to make some of these cuts with a finer blade, the gullets will pack with mud, the blade will minimize much less effectively, and it’ll warmth up. Unable to dissipate that warmth successfully, the thinner blade plate is more likely to buckle and to float within the minimize.
However you don’t wish to use a thick, coarse blade for nice cuts in thinner inventory. A thinner, finer blade is less complicated to make use of in these conditions and can be much less susceptible to blowout on the far finish of the minimize. The sharpening profile issues too. A handsaw’s tooth may be filed in plenty of methods to make them a bit higher at ripping with the grain, reducing throughout it, or doing each comparatively nicely. You possibly can be taught to sharpen your personal handsaws, as I demonstrated in FWW #250, so you may change the submitting sample on any noticed you purchase. A handsaw-sharpening professional can do the identical factor for you.
If you happen to consider the tooth as a row of chisels, a blade filed particularly for rip cuts has its little chisels going through ahead. A rip minimize runs parallel to the wooden fibers, and the forward-facing tooth scoop out these fibers very effectively. When the minimize goes throughout the fibers, nevertheless, blowout is extra of a difficulty on the again and backside edges of the minimize. So noticed sharpeners flip these little chisels barely sideways—with that angle known as “fleam” or “bevel”—to sever the fibers cleanly on each side of the kerf.
As these chisels begin to flip sideways, nevertheless, the noticed turns into much less environment friendly at scooping out materials. So a noticed sharpened purely for crosscutting requires much more strokes to chop as deep. It’s additionally a bit much less correct and dulls extra rapidly. Fortuitously, it doesn’t take a lot facet angle to forestall blowout.
Subsequently, I like to recommend a hybrid sharpening method—with the facet angles touchdown someplace between rip and crosscut—for many saws. This balances clear cuts and environment friendly inventory elimination completely for many duties. I’ve subsequently come to imagine that pure crosscut submitting isn’t well worth the lack of effectivity. As for rip-filed tooth, I like to recommend these just for the devoted dovetail noticed.
Though there are many different backsaw fashions on the market, the three talked about listed below are essentially the most priceless for nice woodworkers. In case you are simply beginning out, observe the sequence outlined right here as you develop into the craft. If you happen to already personal a backsaw or two, this text will assist you to determine what to purchase subsequent.
