All About Pocket Knives

I have an Imperial but it does not have the usual POV R.I stamp only this P 2170537 / 2281732. Can anyone shed some light on this what appears to be Jack knife style ?

to the forum. Since you are new and entered this twice, why not get a good start by doing your housekeeping.

This happens to all of us on occasion so don't feel like I am fussing at you. After all, this is the friendly forum!

Welcome to AAPK. Those numbers are patent numbers. To find out more just do a search on "patent 2170537" for example.

We like pictures of knives here. Please post pictures of your knife so we can all learn from seeing it.
