Medium Sharp Spear - Heavy Duty
Good all round double edged skew. Slightly fatter lines than the F5M. Crisp long or short lines and lazy curves. The HD5M will take more punishment than the F5M. It can be used for shallow relief carving and on hard timber. Can lay tip flat to burn broad, imprecise lines.
