Estwing's unique 5lb Sure Split splitting wedge has a revolutionary concept in design which makes splitting wood fast and easy. The wedge has a fast taper head for easy starting. The Sure Split fins permit extra wedge action and the sledge will continue through out below the wood line for sure splitting.
I have been using standard metal wedges on wood for years. They always seem to lack that last little bit of spread to split the wood. I can tell just by looking at this one that when that 20lb sledge hammer hits it, that extra width from the wings on it will make a very big difference! I've been using a slate bar to finish prying the wood apart, which is a very big help. I won't be using that bar as much now. Just finished a 4ft diameter white oak and wish I would have found this style before.
