When a tool maker or seller talks about paring chisels, we don't mean chisels that can be used for paring: Almost any chisel can be used for paring. Rather, we are referring to chisels that were designed to making accurate paring easy.
Paring is a chisel operation in which the chisel is used to shave precise amounts of wood from the work. The goal here is control - otherwise any chisel and a mallet can do the work. There are three important features of a paring chisel:
A handle not designed for mallets. Of the paring chisel's three features, this one is the least distinctive. To enhance control, paring chisels typically have handles designed to be pushed - thin, long, and graceful - rather than the big and possibly hooped handles that are designed to be struck. Thin handles also put the weight of the chisel at the cutting edge so that the tool is easier to maneuver.
Length. This is the paring chisel's second most important feature. Human hands aren't perfectly steady, especially when trying to push a chisel into resistance. But by making a paring chisel very long, the natural side-to-side movement of the hand's impact is minimized at the cut. And the benefit of the long length is that you can easily sight the chisel to make sure it is at the correct angle to the work.
Low Cutting Angle. This is probably the most important feature. The lower the cutting angle, the lower the forces needed to advance the chisel in the wood. This means more control -- and also less of a need for a mallet. While bench chisels are usually set at 25 degrees from the factory, and Japanese chisels at 30-35 degrees, Western paring chisel show up at 20 degrees -- or even less. This translates to an edge that is very fragile but possessing a superb cutting ability. It's why shaving razors are ground at such a low angle as well.
Of course the low angle doesn't work if the steel can't take the low angle. So the best paring chisels are all made of simple carbon steel, hand- or drop-forged for better performance. A wider chisel takes more effort to push through wood than a narrower chisel does, so the wider the paring chisel, the more important it is to have a low primary bevel angle and a blisteringly sharp edge. Last week I experienced the fragility of the sharp edge when I used the wide I Sorby paring chisel in the photo above and I accidentally knocked the edge against something (not very hard). The edge distorted. I stropped it, but it really needs to go back to the stone.
Up to the 1970's, paring chisels were mostly used by pattern makers for careful final dimensioning of a wooden pattern that would be used for metal casting. The best paring chisels on the market were officially called "Patternmaker's paring chisels" because those were the longest. They were also very thin and slightly flexible so that you could "English" them as you applied hand pressure.
Of course, English toolmakers were not the only ones to manufacture paring chisels. In the US, Stanley made a longer version of their iconic 750 chisels. The Stanley 720 series was their "paring chisel," and while not nearly as thin or as long as the English versions, the 720 comes out of the American millwright's chisel tradition and is typical of the paring chisels made by all the American makers.
Japanese paring chisels have the same long length, but the length is in the handle, not the blade. They are stiffer -- and to my taste less desirable -- but that's very much a personal preference. Millions of woodworkers would disagree with my preference. In reality, Japanese paring chisels are perfect for the precise joinery that Japanese woodworking is known for.
We stock Japanese paring chisels by both Nashiki and Iyori. The former are superb, thin, easy to sharpen, and hold an edge. The Iyori chisels have a triangular section that makes them stiffer, but also easier and less expensive to make.
Back to English paring chisels. When shopping for them, look for beveled sides, not straight sides. Straight-sided chisels are known as "registered chisels." Registered chisels don't have the finesse you would want in a paring chisel. They're typically thicker and are more suited to larger work in timber framing.
Older English paring chisels have nice wide bevels -- more elegant and able to get into corners more easily. Sadly, those dating from the 1980s and beyond just have token beveling at the side and frankly don't pass muster with me. The reason we do not stock any Western paring chisels is that as far as we know nobody is currently making anything that I would consider worth owning.
Older paring chisels have nice octagonal bolsters, which were hand-forged, ground, and harder to make than round bolsters. Boxwood handles were the traditional material for paring chisels. Boxwood is brittle so it doesn't like being struck, but finishes up nicely and has a great feel to it. Incidentally, the traditional way of fitting boxwood handles was having a snug but not pressure fit on the tang, and attaching the tang with a bit of rosin poured in the hole. Both of these features are nice to have, but not requirements.
Because paring chisels are long, thin, and have bevels, they are hellish to make and require the highest skill level of any chisel. Stanley and others solved the manufacturing issues by making the chisels fatter -- at the expensive of performance. The basic problem is that the chisel forge has to forge a long thin straight blank, which is hard to do, and compensate for warping during hardening. After hardening, the chisels have to be made straight again, only to curl up as the side bevels are ground in. It's a no-win situation requiring great skill in forging and grinding. Ray Iles told me that by the 1970's Ashley Iles was forging large quantities of paring chisels, and one of Ray's jobs as a youth was bringing the paring chisel blanks to the one guy left in Sheffield who ground paring chisels for all the edge tool makers.
According to contemporary catalogs, English paring chisels were made in widths from 1/8" to 2". I have never even heard of an 1/8" paring chisel, so it's possible it's wasn't a practical size and was never really manufactured. For me, larger sizes -- 1 1/4" - 2" -- are the ones that get the most use, but since I am not a patternmaker, nor a Japanese temple builder, the main use I have for them is paring a mortise to a scribe line after chopping, and occasionally trimming a surface. For paring the odd fat dovetail joint, I use my regular bench chisels. Instrument makers also love paring chisels for the precise formation of wooden parts. With that in mind, what I recommend is that if you see some wide English paring chisels, in decent shape, that are fairly long, snap them up. But don't lose sleep if they seem elusive.
P.S. We expect to get a shipment soon of Ashley Iles beveled edge chisels with the wide 2" size back in stock. Uber long paring chisels might be a discretionary purchase but I think wider bench chisels are very useful. While you might not use them every day, having wider (1 1/2" or 2") bench chisels, are especially useful for cutting clean joints at a scribe line or cutting wide base between pins on a dovetail joint. As with paring chisels, with wide chisels of any kind, a low angle, and keeping them uber sharp will make them much easier to use and get the results you want.

Although not true paring chisels, the "Round Back Dovetail Chisels by Ashley Iles" work very well for paring and I find them very comfortable to hold. Be nice to get them wider than 1".

Thank you for a well written, informative article!

I can highly recommend the paring chisels made by Dave Jeske at Blue Spruce Toolworks located in Portland, Oregon.
I have a couple of Henry Taylor "Long Thin Paring Chisels" that I purchased only about 2 years ago. But I have never gotten a chance to use them yet.
As i said at the begining of the blog you can pare with anything. Including both Henry Taylor or Blue Spruce paring chisels. Both are fine chisels, just not in the same league as the no longer made, much longer, thinner, nicer forged, lower angle English antiques - if you can find them in good condition and at full a length as possible.

The best paring chisel you'll ever use is an 8mm (maybe 12, depending) No. 1 sweep fishtail.

I have 4 of the Sorby paring chisels (1/4, 3/8, 1/2, and 3/4 inch). I really likes them for trimming the bottoms of dados in carcass sides - but not for dovetails - for that, I use my Ashley-Isles dovetail chisels. These are, essentially, a short paring chisel with a modified side-grind.

I have 3 sizes of the Sorby paring chisels - 1/4, 1/2 and 3/4. The two smaller sizes I ordered thru Amazon (provided by a 3rd party in Ohio). Both were received with a distinct bow in the blades (beveled side concave). Don't know if this happened in transit or came that way from the factory. Both cutting edges looked like they had been formed with a hatchet which is probably a reflection of diminished QC in the UK. However, with the steel soft and thin, they cleaned up readily. Because they are so thin and flexible, the upward bending bow seems to be of no consequence, as it is easy to hold flat while paring (I pare with one hand on the blade and one on the handle). The 3/4 chisel was obtained thru LV and had less distortion. The only minor negative comment is that although it is marked 3/4 it is sized metrically and is about 1/32 wider. If you want to pare a 3/4 dado for pine obtained at Home Depot, this tool won't work. But it would work well for typical hardwood thicknesses.

Back in the 80's I started as an apprentice wooden boat builder in New England. I put together my tool bag from yard sales and antique shops. Over the years since then I've collected a full set of Witherby paring chisels, from 1/8" to 2". So, Joel, if you want to see a 1/8" chisel, I'll be glad to send you a picture. I love the Witherbys, they sharpen well and hold an edge superbly. Some of them I had to turn new handles for and I used white oak because that's what we had shed's full of at the boatyard. Over time I've collected quite a few old and new chisels--registered, mortise and timber framing--along with a couple of large slicks. The Witherby's remain my favorites.

Joel, have you used the Sorby paring chisels? My 1 1/2" version is quite flexible and long with wide bevels and performs almost as well as my narrower, vintage ones.
