Item Title
Description
This item is a chisel made by Yoshio Usui, a rare blacksmith in Japan who produces chisels with all HSS.
His work is sold under the name "Sukemaru".
This item is exactly the same, but the name is the wholesaler's name.
The item is exactly the same except that the engraving on the blade is different.
It is a little more expensive than the regular Sukemaru.
Blade : 9mm
42mm
length : 220mm
Steel : High Speed Steel (HSS)
black smith : Yoshio Usui
Origin: Japan Niigata
Handle : Red oak
The characteristics of this chisel are the hardness of high speed steel and the two grooves on Hollow back.
This groove has a role.
1, Less material to remove when you flatten the back of the chisel.
The hollow back makes it much easier to get it flat and makes sharpening it in the future faster and easier
2. Helps the blade to be more precisely horizontal and vertical when processing wood.
Processing this Hollow back requires high technology.
It is more effective if there are more grooves.
This feature is unique to the Japanese chisel.
HSS is so hard that it is difficult to grind, but you can grind it with a diamond whetstone.
You can keep the sharpness even in hard work.
It requires skill, but it can be sharpened like White steel.
I will list the review of the buyer who used it.
”I finally had some time to sharpen the HSS chisel
It sharp easy on my diamond stones and it got very sharp.
I then tested it on some American white oak and some Baltic Birch plywood which has many layers. It held up for about 50 hard hammer hits before the edge deformed & dulled. I was happy with the performance as those are 2 very hard materials and the plywood has glue and who knows what else in it.”
