Some wheel-type marking gauges have the advantage that the cutting edge is at the very end of the stem. However, some people (me included) do not get on with that kind of gauge. This is an alternative approach, with a cutter mounted in a hole at 45 degrees to the axis of the stem and secured with a grub screw. The cutter is made of 3 mm diameter silver steel rod, unhardened but still fairly hard and capable of being filed by the user to any desired point shape. The hole in the stock has a slug of nylon to prevent metal-to-metal contact between the locking screw and the stem. The wood is mahogany, re-cycled from an old piece of furniture.
