What JDW said. There are some good options out there with bits. They will require some bucks, but be worth it. The wide selection will fit most everything. Push come to thsove, they can be reground to fit particualr applications.

At the the lower end are some of the wood handled sets with 6-12 fixed blades. In my experience they don't fit a thing and ultimately are too soft to regrind to a usable, durable tool.
