I would like to write something about Benchmade, but I don't because I don't want to deal with a fan who will defend it as if it were his father's company. If it's really $600 you should stay away from it and go and buy premium brands like Crk, Olemic, Spartan, Hinderer, Les George etc. Even from brands such as Maxace and Rike, you can buy incredible knives for that money.
Note: I am not against the free market. I would like to point out that thanks to the free market, you can buy better quality at a cheaper price.The free market allows you to set whatever price you want, but you face the consequences.
