More states in the US are decriminalizing switchblades, yet there are many other methods of opening a folding knife with one hand such as studs on the blade or groove to make it easier to open.
I am not talking about the ones that have double edged blades but rather standard folding knives such as this one,
where the only difference is how you open the knife with one hand.
I have used a regular folding knife in the outdoors for whittling, skinning animals, cutting marshmallow sticks etc for years, and I am happy with my current one, but would there be any advantage of a folding knife with a switchblade method of opening?
