Stone Hamer Vendor Recipe - A change?

Well, I like the idea behind it. But I think it's not a very helpfull recipe for highlevel players.

First: You need 4 whetstones to get a +20% stone hammer.

Second: You need Stone Hammers and in my opinion it's not fun at all farming lvl 16 Maps as a high level player


So what I want to suggest is: Instead of only giving the option to make it with stone hammers, why not making it possible with every kind of hammer (mace)? You still would need the whetstones, but at least you could use other weapons as well

I think the intention is giving low level players a chance to get better trade items. A stone hammer should be worth like 4-5 alterations with current chisel prices
