started using these knives in 70s.not the slick lookers as much as case but great users.skinned 3 mule deer with a folding hunter& it would still shave hair.collected large bunch in 80&90.s these knives were made for hard use and really were enduring.some history on the brand;were 1st brought into this country in1932 or so by forrest cruse in austin tx. carl schlieper was the founder in 1800s.made many tools besides knives,razors,& sissors.they had large exports to usa ,s. africa, & australia .peter schlieper is the last of the bunch to date.mark cruse is a friend of myself and still is jobbing eyes to wholesalers along with other brands.he told me that the trip hammer and tempering was 20% of knife costs at one time.some of the early eyes were totally mirror polished.i,ve seen some that even had a mirror polish on the inside of springs within the frame.
