The box was labeled as assisted opening, so I think anything with a hole or peg would be considered that (not just with spring).
Just to clarify- an assisted opener
assists you in opening the blade. To qualify you must start to open the blade (usually to about 30 degrees) and then another force (spring, cam...) takes over and finishes opening it for you. The difference between this and an automatic is that with an automatic you depress a button/lever and the blade opens due to the mechanism, instead of you actually moving the blade yourself until the action takes over. No matter what labelled on the box- it is the knife that matters. A common thumbstud/ Spyderhole knife with no such mechanism is a regular knife. Always trust the knife as opposed to the box- one is never sure if the box actually belongs to the knife until the knife is inspected. As for your choices- I would agree to get one for you, one for him- and definately check out the delica and Native(my personal choice for your purposes). And kudos for actually researching and taking all of our suggestions in a polite, and pleasant manner.
Good luck and happy knife hunting- you better not come out empty handed now that you know where the knives are hiding (HERE!)
