I must be bored tonight.
I didn't want to put more notches into my bowl blank, so I found some 8/4 white oak. Same 3 mm Imai bench chisel as before, and I still haven't resharpened it.
I chopped a bunch of notches (these weren't sawed carefully enough to call them dovetails). But it's good enough for a test of chopping ability and edge holding.
Again, given the width of my 3 mm chisel, I had to take 2-3 passes in each notch, so it was at least twice the chopping I would do if I used a properly sized chisel. If I'm calculating this right, the amount of chopping I did here is close to what I would need to do for all four corners of a dovetailed box made of 1/2" white oak with a properly sized chisel.
After I finished the chopping in the 8/4 white oak, I made some more endgrain shavings from that same piece of scrap pine I used before, which you can see. Again, no sharpening since before I chopped the dovetail in that cocobolo bowl blank. And still no chipping.
It felt like the chisel was slowing down a bit as I got towards the end, but maybe my hammering arm was just getting tired. In any case, the chisel was still sharp enough to make clean endgrain shavings in pine.
The bevel angle on this chisel is 29°, which how it came, and is pretty much the same as the Lie Nielsen bevel edge socket chisels. I don't use a microbevel.
