Basic tools are made of carbon steel, not stainless steel (which is softer). The key to quality in a woodworking chisel is the steel. Keep your eyes open and you might be lucky enough to find a piece of history that’s perfectly useful today.

If the chisels used where for metal or are wood chisels, the modified method used for wood chisels below, would be okay for the intended usage.
The more pressure you apply, the faster the cut rate. Use a slow speed bench grinder with a cool-cutting wheel. The first grade quickly removes the rounded edge. Hold the blade freehand or, for more precise results, in a honing guide at the correct angle. A paring chisel has a thin blade beveled at an angle of 15 degrees.
The more secure the fit, the more control you will have when pushing with force into the wood.
When you pare, you are not taking off large amounts of wood, so you can pare with or against the wood’s grain.
This hand controls the forward movement of the chisel.
That lubrication helps it slip through hardened metal grains. I grind a fresh edge with a 60-grit white aluminum oxide wheel and hone it on a coarse water stone. Most tools and knives like 60 degrees, but the secondary bevel plays a big role in performance.
I don’t need fancy machines or gadgets. I want to shape the steel quickly and avoid heating up the tools. Hold the chisel at a 45-degree angle from the face of the metal, with the bottom bevel of the cutting edge resting on the top of the vise.
Cut halfway through the piece, then flip it over and cut from the other side. The holes should remove enough material from inside the cutout so you can clean up the edges with a chisel. The bottom bevel of the cutting edge should rest on surface of the surrounding material. Proper honing of a chisel relies on properly flattening the back. A concavity on the back is not as serious a problem as a convexity. The cheap stuff cuts too slow and wears out fast. Apply the sandpaper to both sides of the glass-this will prevent the glass from sliding around.
Practice with your least-favorite chisels first.

If you cut through to the metal right under the point where the hammer will strike, you’ll create a leaf-spring that will absorb part of the blow.
Did seem to dull quickly but was still useful for vertical joints. I think production, quality and profits.
A belt sander and or a grinder with the proper type of grinding wheel would do the job better and fast.
3 Piece Mortise Chisel Sharpening Set
A wheel for honing burrs would be a nice addition also. Visit any used machinery shop(s) or local tool shop(s), resellers, of machinery. Would make a nice small investment for maintaining the current chisels and any new ones purchased. I once was doing some doors and had my good chisels for the mortise work. I loaned a chisel to one of the guys and – a little later – saw him using it to take up a threshold.
He was pounding it with a waffle faced hammer and driving it through any nails that got in his way. Something i can;t stand is a tool that’s been used for the wrong job. To re-harden a blade, heat it to the critical temperature, which would be around 1400 degrees. Quench the blade in water, and after it’s cool enough to touch, temper it at 500 degrees. Heat it until it turns a pretty straw color, and then set it aside and let it cool.

I think we’ve already covered exactly how it works. I have never seen this chisel used to break concrete or masonry, your right. Very interesting claim, would love for the thread to figure out exactly what it means. Don’t yet see how the flat chisel works yet if you drive it straight into a surface. Winter heading soon and the amount of concrete needed to test, it may be awhile seeing how it works. I place it against the wall, it does not show it is calibrating nor does it detect anything. I checked) but it still does not work. Sculptors use a spoon chisel, which is bent, with the bevel on both sides. The direction of the taper in the blade determines if the chisel cuts deep or runs shallow along the joint.
The blade geometry is defined by a semi-standardized numbering system that varies by manufacturer and country of origin. Putting these pieces together, two numbers are used to specify the shape of the cutting edge of a gouge, such as a ‘#7-20mm’. All of these specialized gouges allow a craftsperson to cut into areas that may not be possible with a regular, straight-bladed gouge.
The cutting shape of a gouge may also be held in an adze, roughly as the shape of a modern-day mattock. Gouges are used in woodworking and arts. Standard bench and butt chisels are traditionally ground at the factory to 25°, and this is fine for most work, but the edge will last longer if you add a 5° microbevel to make a 30° cutting angle.
The distance from the guide determines the edge angle. Avoid overheating while grinding the bevel.
Your finished bevel should be even and straight across the blade.
Mortising and firmer chisels take a lot of impact stress as they’re chopping and prying – their edges will tend to last longer with a higher bevel angle.
If the edge holds up well, you may be able to reduce the microbevel and improve the cutting action. As you strike these chisels, keep in mind that the narrower ones do not need to be hit as hard as the wider ones.
So adjust your hammer blows accordingly – your chisels will thank you.
