New Vintage Giessen & Forsthoff 3 5/8" Pen Knife Solingen Germany

New Vintage 3 5/8"  pen knife with carbon steel blades Giessen & Forsthoff Solingen Germany est 1920.

Black composite scales, brass pins and liners, pen blade and little bit unusual secondary blade (screwdriver?), mechanics are great, (walks and talks as they say) blades are countersunk, that is flush with handle at joint when closed (a higher end feature).

Found with other knives from Solingen mostly made in the 70's and 80's but as of right now there is no precise date on these, it is very likely these are older than 70's as the work is very nice but the handle material is not especially high end. 

These knives are unused and offered in as found condition which is very clean but might include tiny dark spots on blade.

Closed length is 3 5/8" and open 6 3/8" 1.35 oz
