Interesting metal wedges that I have saved.

The OREGON company ( a chain Saw supply outfit) used to sell a wedge that they called the "Wood Grenade". I actually bought one and it really did work well with wood that was normally difficult to split. I either lost it or it got stolen during one of my moves and I'm not sure which it was. I wouldn't even mind having another one of them.

There is a lot of differences in how certain wedges work and there is a lot of difference in how some mauls work too.

Thank you very much for participating in this forum. I too have personal experience with 'Wood Grenades' and they're somewhat less positive than yours. These ain't so sweet when you try to use one on a knotty piece of Rock Elm or Ironwood. Just so you know 'Wood-splitting wedges' (such as 'Wood Grenade') have nothing to do with the finicky-type tapered wedging goodies that folks use to 'hang' (secure) an axe head onto a haft.

I've had a similar problem trying to get these to stick in London Plane. What I ended up doing was using a thin cutoff wheel on my 4-1/2" angle grinder and re-cutting those barbs, sharper and deeper. Just cleaning the coating out of them probably helped. After that it bit much better. But I still prefer standard square-taper wedges re-ground with a sticky concave grind.
