I've built many hundreds and hundreds, if not more, of elk/antler handled knives.
In the box in the foreground alone I'm counting 9, it's a very popular handle material for me:
Counting 14 in this batch ready for the handles to be hand sanded:
Five out of twenty here:
The vast majority of my sales are to cowboys/ranchers, guys that aren't particularly easy on stuff.
Ya can see my own personal elk handled EDC there on my waist with the thongs hanging down, if ya look close. I carried this knife about 3 years doing active cowboy stuff:
Here it is posing in some no name cowboy bar in the middle of nowhere AZ.
I have found elk/antler to be a very durable material and practical as well as good looking. Is it bullet proof? No, but this one survived the lawn mower:
Had to build the customer a new sheath though. Many folks say that the synthetic handle materials are bullet proof, they're not:
Anyhoo if ya like elk or antler, it'll work for ya. I don't recall every repairing or replacing an elk handle and thats on a lot of knives that have seen a lot of life.
