Sailing folks call it a rigging knife, but have the same discussion/disagreement about point vs no point. The old rules were that an enlisted man could not have a knife with an edge over 3", and the point had to be a blunt Wharncliffe style ( Usually reshaped from a broken off tip). This was to protect himself and the sails from accidental damage and injury. In actuality is was more to reduce the severity of wounds when fights broke out.
Unless a special request is for a Wharnie tip ( re-enactors and tall ship sailors), I don't make the blunt tip blades. On a rigging knife, I use a thick spine, a steep angle tanto/chisel tip, and a secure sheath.
Just a side note about the tip shape we call "Tanto". It is actually called kamasu , or kamasu kissaki. This type of tip went out of popular use on tanto blades 500 years ago in Japan, but has reappeared now as the "American Tanto". Actual tanto tips normally curve up to the spine in a smooth taper, very similar to a kitchen knife. While katana and wakizashi tips look similar to kamasu, they have different geometry.
I realize that everyone will still call this "tanto", but though some folks would like to know the actual name.
