Wich of these folder knives do you think that have the strongest blade and wich the strongest lock?.

I would chose the EL01 any day of the week over a "serious" Spyderco Tenacious for heavy duty use. But I would suggest a full tang fixed blade knife, if you already know that you will be abusing it.

@cone: It's not Paisley, but he rather wants to know what to purchase with his winning coupon. What gave you the impression of Paisley? I don't see it.
