Stitching Groover is a specially made item assembled with a specially made wooden handle.
It is sold with a Polishing Compaund as a remedy in case the sharpness gets worse.
Please use it as your own original tool that you cannot find anywhere else.

Most older conventional stitching groover’s blade didn’t cut well and weren’t treated with rust-proof process so the whole blade part become rusty and you couldn’t use it. The recognition of Stitching groover has been commonly accepted on the market, especially by beginners.

We aimed to improve all the disadvantages and create a tool that anyone can use successfully and for a long time.
Here are the key points in the development process.
(1) All the blades are assembled by test cutting with leather.
(2) After cutting, a tube is attached to the blade to protect it while it is at its sharpest.
(3) The entire blade should be coated with black coating to prevent rust.
(4)The width of the non-slip part of the body should be thicker.
The body should be thickened so that it can be fixed securely with less force.
(5) The shaft of the body should be made of hard steel.
The blade should not form a square shape due to the force when it is fixed.
①Ebony has a natural color and the natural wooden handle can be colored in Tan, Mahogany or Walnut.
Only the Ebony handle has two lines on the lower part of the handle.

②The cap on the handle is made of brass. It is made by hand on a one by one basis and there is a line on it to improve the appearance.
And also, the caps are fixed with tiny nail of brass.

③For your reference, ③is our standard color.
