All About Pocket Knives

I have a La Vespa pocket knife it has a really strange shape blade on it. It is a one bladed knife . Looks like maybe horn handles. I just can't find any information on them. Any help or links would be appreciated.
Thanks Abear

Italian circa 1950's. see this one.

A tip: Explore AAPK. There's lots of neat stuff here.

That is a horticultural knife designed for grafting trees.
I have one that is almost identical to yours, that was given to me by a retired orchardist.
Mine has totally black scales and is marked "Kuker made in Italy"
Mine, like pretty much all of the horticultural knives, are bevelled only on one side of the blade.

I am pretty sure that mine is a lot newer than the 1950s

That odd shaped blade, is designed to help in gently separating the bark of the tree before inserting a bud when doing a bud graft.

I just checked.

It is possible to buy a new Kuker knife that looks just like yours for 15,99 Euros
