Made from M2 tungsten molybdenum steel, hardened to RC 59-62, M2 is often used at somewhat higher hardnesses for woodturning tools, where it's excellent abrasion resistance provides superior edge retention.
The hafted handle is made from pakkawood - a resin stabilised wood composite, with solid brass rivets and spacers.
In an ideal world, a pair of marking knives gives the choice to work up against left or right templates when laying out or transferring marks. With a spear point knife you can just flip it over and cut the other way.
The tip of a spear point is a little finer and more delicate than single bevelled knives, perfect for layout work, but if you want to carve or make heavier cuts in veneers or leather for example a single bevelled blade is a better choice.
