The blade on the one I posted above is just over 36 cm / 14 inches in length and just under 4.5 cm / 1.75 inches wide at the base. The fullers are so deep in this 4.5 mm thick blade that in just a few foci, light will pass through a few pinprick sized holes in the blade where fuller meets fuller. The smith obviously had to remove a lot of metal and did so with great precision. The hilt, though plain, may well be made of rhino horn and is very well shaped and fitted. The iron rivets are nicely faceted and over a cm high. I have never had a scabbard, so unfortunately, this exceedingly sharp dagger is sheathed in newspaper bound with masking tape.
I found it at an arms fair several decades ago; I was told that it was part of a collection of pattern-welded items that was being dispersed.
