The only wedge I have ever bought is this grenade style one. It has split open everything I have ever thrown at it with less effort than a regular triangle shape one. I don't actually own any regular ones, I have always used railway spikes that I find on the old abandoned spur line out back of the property. ![[Hearth.com] Favourite Wedges...
