This one today and it may be the oldest small Tinker I own. I have older SAK's but this is the oldest two layer. Someday I hope to grab one with scale pins
The bottle opener has the beveled edge, similar to the edge on the awl.
The can opener has the +PAT stamp on it.
The square phillips is not the tin can opening phillips. This is solid and has the file incorporated on the side.
So to sum up things, clip secondary, +PAT stamp on the can opener, beveled edge on the bottle opened, no eyelet in the awl and one thing I noticed is that the shield is closer (higher) to the tang stamp end of the knife's main blade
over all, it's in very good shape. I did have to clean it extensively as a few of the blades where hard to open, sticky like
but well worth the effort
