This is an excellent hammer that does the job well and I am happy with it. The only slight drawback is the relatively light weight of the hammer, even for one of the larger sizes (I bought a size 3). If you intend to use a hammer for, say, hammering in stitch holes for leather-work, I would recommend a size 4 and above. For more careful hammering, say for jewellery of some kind, a size 3 or below will suffice.
All in all, an excellent hammer that is at a good price and lovely quality, just could be a little heftier.
