All About Pocket Knives

I know I have seen this mark before but I can not find a maker name for this mark.

That is Peter Altenbach & Sohne.

Thanks for that information. Seeing the maker mark name in German helped me to find it in my Knife Collectors Guide in English. Altenback would not have jumped out at me.

Thanks for your help.

Glad to help.

I like the Boker Applegate Fairbairn knife in your avatar. I have one without the teeth.

It's a great knife with or without the serrated teeth.
