I stumbled upon these in the Black Friday isle at a big box hardware store for little bread. The key body is steel. Still in the blister pack. I was looking for a deal in 2d Maglites, deal was disco, and found this. I will either gift it or open it myself. I have a similar lock back key and it is robust but I don't carry it, just marvel at it. It would ba the fourth knife carry after: Buck Marksman, Buck 424 and Brit folding card knife.
