I bought these based on glowing reviews with the intention of using them as spare chisels in my wood shop. It turns out the steel is too soft for that - these really are carpenter's chisels. My first clue was a metal cap over the red plastic handles, indicating they were meant to be hit with a steel hammer. 3/4 inch bit - "full machining". First I leveled the back with a coarse diamond stone, a fine diamond stone, an extra fine water stone and finally an 8000 water stone until the back was polished to a high gloss. Bevel I went through the same series of stones - coarse and fine stones at 25 degrees and water stones at 30 degrees to give it a safer secondary bevel. This process always creates burrs on the back and I polish them with stone 8000. I took this razor sharp chisel to the workbench. I took a 2x4 pry bar in a vise and snapped off the end grain wood - not bad! I tried another shave but this time it didn't cut. , I felt the pointed edge bend, so I went back to the rocks and refined the damage. The next 2x4 test went the same way as the first. They really aren't designed for carpenter's chisels. However, if you are looking for carpenter's chisels, I trust they will serve you well. You can tap it with a claw hammer to remove ugly old floorboards or pry open an old door frame without affecting your more expensive chisels. That's why they're available in my shop.
