I prefer frame locks ( assuming proper execution ) . I like the axis lock , but Benchmade wont sell the pesky little springs . This means shipping the poor beast internationally for repairs . I once had nearly 50 Benchmades , now I only have two . I don't have a great deal of faith in liners except for light duties , duties that a slipjoint will do about as well.
I had a T mag and liked it , problem was it attracted all kinds of crud and small denomination coins .
