Hawaiian Koa wooden handle & sheath.
In cooking knife world, they are just left hand right hand knives, but in woodworking world, we need the both of them does not matter right hand person or left hand person.
If we are right hand person with the right hand kiridashi, and trying to scrape the wood, the blade edge bites deeper and deeper unless we change into the angle to be outer side of the wood.
However, if we are right hand person and using left hand kiridashi, it is easier to shallower scraping.
Therefore, we need the both the left hand & right hand kiridashi, if we have detail wood work.
