Hi Chisel,
When I was 15 I had my first "real" job at a place that was a combination bakery/campground/nursery and also had about 2 acres of indoor commercial rose garden. The workers who harvested the roses used folding Victorinox knives with a single "sheepfoot" blade, they looked like this SAK Gardner but with black scales,
