My bad. You’re probably correct considering its been 8 years since I’ve cut any keys. But i did have about a decade and a half of key cutting experience. I used to be able to cut 3 keys at a time if the chuck would open wide enough mostly just with the wr-1/kw-1/ar-1 and sc-1 blanks. I don’t miss finding those damn brass shards in my feet after work though

I did clarify in another comment that it did look like an assa key after this comment. Sometimes those little round keys for special cylinder locks and po boxes were the hardest to figure out.
