Geological Hammers and Kits
If you're looking for a great hammer with a pick, this seems to be the best one I've found. Hammers aren't exactly high tech so I don't have much to say except that this one will last.
This is the second-best hammer. Quality wise it is the same as the #1 choice, except that its a bit shorter, which means you'll get less power out of it.
Hammer Kit #1
If you're looking for a fun kit then this one checks quite a few boxes. I'd personally suggest buying the items individually if you're looking for quality, but this is a great bang for your buck if your just starting out or wanting it as a gift.
Hammer Kit #2
This kit comes with a lot of stuff. I don't think the spade looks like it'll last long, but just like the #1 kit, it would make a great gift or starter set.
