I am not a collector at all. I have purchased all manner of knives over the years and all I can tell you is that the only difference that I have ever noticed between the high dollar knives and a $30 knife is that I feel reluctant to actually punish a expensive knife because I dont want to have to replace it.
The only time I can see spending extra money on a folding kife is when you prefer one type of locking mech over another. Axis locks are gonna cost you.
