I finally got round to making a small chopper that also doubles as a digging implement. Given that a steel trowell starts off at ~100g~ and that is always a bugger to use due to the short handle, I thought that there must be a far better way of doing it.
Started off with a Fiskars Brush hook, about 450g, cut the end off it, and ground it on a wet and dry grinder to shape the tip. I also bevelled the edge opposite to the cutting edge to take the pressure away from the blade to stop it blunting. Didnt sharpen the other edge because I think the blade is meant to cut this way around only, and I didn't wish to pressure the handle.
All in all I'm pleased. Its 350g now and easily and quickly diggs to a good depth due to the long handle. The tip actually does not penetrate deep enough into compacted ground to blunt the edge much more than 1cm,so it stays sharp. The blade itself cuts green wood easy, and drywood easily with a diameter of about 4cm, any more and the flat edge has trouble. A bit of tape should further protect the edge.
The actual steel that the hook is made from is hard, really really hard, and isn't easy to grind, I believe its boron or something. I highly reccommend the wet wheel to all, even if you only get a wet honing wheel, it rotates only slowly so you cant injure yourself, but is powered so you can apply lots of pressure or a little and do delicate work, admitted its not as quick as the grinder, but the metal never ever gets hot, and is an easy way to rough sharpen anything you like.
