What is your most expensive knife? As an 8th grader, my choices are limited and I have to buy most of my knives unless gifted. Problem is I like the expensive knives! But anyway, my most expensive knife is a Helle Temagami with a price of $180. Took me 3 weeks to get that much money, but was well worth it. My second most expensive knife is a ESEE Laserstrike and was about $115. The rest of my knives are Mora and Marttiini knives. All of them are good and non are Chinese made!
