Marketty Nylon and brass multifunctional hammer, 4 interchangeable tips, 25mm double headed nylon rubber hammer, suitable for jewelry, leather, wood or spark free work

Lots of issues from other users here but my experience it pretty good. Head is tight on the handle and hard to imagine it coming loose. This hammer is for light gunsmithing work not driving framing nails. Rubber handle is a little small in diameter but I have large hands and I like it. Heads, especially the brass and aluminum loosen (unscrew) in use which is very annoying. My solution was to buy two of these (come on, they are pretty darned inexpensive) and use blue locktite on the face threads. This way you have two hammers, four different, semi-permanently installed, hammer faces plus a spare set of faces if one gets damaged. This solved the loosening problem for me and I don't have to keep changing heads. The thread holes in the head on mine were dead nuts centered. Guess I got lucky! I don't expect this hammer to last a lifetime...but it just might and if it doesn't, $16 isn't going to break the bank to buy another one! I would recommend this hammer to a fellow gunsmith.

Size. Damage resistance. Use.

Decent build quality with plenty of hammer surface options. Using for guitar building. Do question durability of some head materials and the screw shaft of attachments for long term, but should be good for quite a few jobs. Handle is grippy and comfortable. Overall weight is perfect for my purposes. Considering price, I'm happy with value, quality, comfort and longevity.

I recently bought this hammer to give me a few more options than my other gunsmithing hammer which doesn’t have multiple heads (it is traditional brass head with a wooden handle). The heads on this hammer are easy to swap out and are the right diameter for most gunsmithing work. The polymer, hard rubber and aluminum heads are a certainly a nice addition to brass when you need to make sure you do not mar your firearm (which is easy to do with some firearms due to pin locations like those on ARs). The weight of the hammer varies depending on which heads you have attached. It is about 8.1oz with the brass and aluminum heads, 7.5oz with the brass and polymer heads and about 6.2oz with the rubber and polymer heads attached. It is a little heavy for pistolsmithing work (I generally prefer a 4oz hammer for handguns) but you can get it down to around 5.5oz if you use only the polymer or aluminum head on one side with no head on the other side. If anyone is wondering, the brass head weighs 2.3oz by itself so if you could equip it with two brass heads, you would have a fairly hefty gunsmithing hammer at around 9.7oz. The handle is relatively small diameter but allows for a secure grip as it is textured rubber. Right out of the package, it had fairly noticeable molding seams on the handle but those were easily smoothed out with a small piece of 400 grit sandpaper. If there is anything to complain about, it is the shape of the striking face on the aluminum and brass heads. As you can likely see in the pic, they are very rounded and this tends to make the hammer glance off of punches unless you hit dead center. I will likely chuck the heads in a drill and press them against sandpaper to slightly flatten them at some point. For whatever the reason, the polymer and rubber heads are a more typical, flatter shape. Despite the seams on the handle and the overly rounded strike faces on the brass and aluminum heads (all problems which can be easily fixed), the hammer is still a deal considering it comes with four heads and is very sturdy. For comparison, my traditional brass headed, wooden handled smithing hammer was around $22

Hey what can I say about this hammer that's not the obvious. It's bangin! No, I mean that. The pin heads I use it on, go down pretty quick. Look, you have some pin head, and some times when the punches alone are not enough, you gotta use this hammer. A couple whacks and it's done. I like the changeable hammer heads too. There's 4 heads to this hammer. A metal, a brass, a rubber, and a nylon. Use which ever you need to. Leave visible marks, go the metal, but if not, there's the nylon. No marking up with that one. It is a reliable hammer and I have already used it quite a bit in the short time since it was delivered and I recommend it! Oh, did I mention, I do some gunsmithing work. :-)

Like that it has changeable heads. Not very heavy so to not marr the surface of what is being repaired.

Great gun smithing

Nice little hammer for working on delicate items. I bought this specifically for my firearms assembly and cleaning
