Here are some Snakewood and one Indian Rosewood marking knives I just finished making. The blades are only 5/16" wide and are much nicer for small work than my 3/4" wide bladed Lee Valley. While the LV works fine for most uses, it is just too awkward for marking the pins on really small dovetails. The steel for the blades is O1 from MSC Industrial Supply and the ferrules are brass from LV at about $.16 each.
