A quick GOOGLE search yielded Columbia Marking Tools
What sizes did you order? 5/16 & ? What material can you mark? Aluminum up to steel? What price range is it?
Is that pick of a stamp in some sort of protective material ?
Yeah, it is a wax like protective covering over it for shipping. It comes encased in that stuff and covered with oil on the inside.
This is the model I bought. You pick the lettering height you want and then how many letters on the stamp.
I have not tried to mark any tool steel with it, so IDK how it would do on hand tools, but pretty much anything metal or alum it will mark. These things appear to be top quality. I think they can do all sorts of designs as well. I am temped to see if they will do a tiny little dick with balls in an arrow shape to use as a match mark/index mark punch for work. Something small enough that it looks like an arrow at a glace but if you look closely you can see I'm leaving little dicks all over machinery that I work on
One with real small type, especially some sort of unique proof mark type design would be great for marking firearm receivers under the stock for ID purposes should they be stolen.
It took about 2 weeks to get it after I ordered it and they sent me update emails all along the way like when it went into production, out of production to shipping....
