Some companies laminate with 420 with a good steel in the middle because it's soft and will add durability, but lower end companies use it for price. If you're looking for durability, go with a carbon steel blade like 1095 or 5160. It'll be more durable and hold a better edge, and there are plenty of them like that Gerber for $100 or less. Check out knives by ESEE and TOPS, for example.
