HDIDS609 Hammerless Metal Stamping Kit, 1/4" 39-Piece Alphanumeric Steel Stamps, 5000 LBS Force, A-Z, 0-9, Heavy-Duty Case, USA-Made, Number and Letter Punch

Good quality and reasonable price. When you use it, for best result, try to place accurately stamp on the marking surface. Exactly perpendicular, to have a full imprint

Does what it is supposed to do. Imprints clearly on metal and wood. Downside is that I found it hard to maintain alignment during pull-back. For single letters where position is not critical it is fine. If you want an accurate, evenly spaced layout it may be better to use standard stamp with a hammer. Risk of double tap may occur with this. If anyone has a method to keep letters aligned please post your technique.

As described and good quality.

It was not like the one I thought, The spring is already damaged after a few use, it is not easy to use after all

These stamps are very small. When opening the box you get a warning not to hit with a hammer as they will chip with flying fragments. These are not for heavy work. Not what you would use in a shop if you were at work. Good for soft materials only, like jewelry.

This is super nice and great quality

The tools are good quality as well as the case, but the letters/numbers are on the larger side. Thus combined with the spring hammers lack of power makes it unable to mark steel. It can barely mark aluminum.

Other reviewers tried to tell me, but I had to see for myself. Sure enough. Great idea. Well built, sturdy, excellent quality. Sadly, it just doesn't work like expected. At least not on hard surfaces. May be fine for softer metal, but even then, it is harder to use than expected.
