I am going to reach on out on a limb. It would have to come from the factory .......sharp.
I'll say it, while the SOD was sharper than the other knifes (appreciate that) I have received from the yard, SY blades typically are not very sharp. Don’t get me wrong they can cut you finger, just not off. The fact is folders need to be extremely sharp, as its main use is for cutting. Most the knifes from SY have to be touched up in order to really get the desired effect. The idea of a folder is great but I would want it hair popping sharp from the bowels of the dumpster.

P.S. It would be called the Scrapyard Biter, Scrapyard Fang.
