People have been putting hammer heads on handles for a few thousand years, and this is certainly not an improvement. It weakens the handle where it needs strength the most. Lots of fun ideas for anyone stupid enough to think so.
Ich habe genau den selben Hammer. Es ist ein russisches Fabrikat der Stahl ist dementsprechend sehr gut. Den Stiel dafür habe ich aus ganz gutem Kiefernholz selbst gefertigt. Nachdem ich den Stiel angepasst habe wurde dieser unten mit Knete abgedichtet und anschließend mit Epoxidharz (Zweikomponenten) ausgegossen. Der Stiel hält bis heute auch ohne Keil.
Gotta disagree with this. Wedges work. Set the wedge tight, recess the wood with a dremel, a four in hand rasp, or a gouge down into the head about 1/4 inch and mix up some fiberglass or epoxy and seal it by placing it upright in a bench vise, bring the poured glass up to the spill over point, allowing it to run down into the hammerhead's innards. I seal the base of the head with some blue painters tape to any stop run out. Allow 24 hours for a good cure. This works with other handles, axes, rakes, homemade tools of all sorts. I made a long handled flap hoe to clean out culvert pipes and you don't want to lose the flap hoe head off of the handle when it's 8 feet into a culvert, so your idea may be great for that, just not for striking tools, but the fiberglass seems to holding up just fine... Also, consider not using handle as a striking tool.
