Heavy duty logging I'm not so sure
I felled an Ash tree, approximately 34" diameter above the root swell, and I started smacking these in place along my back cut, and was surprised at the amount of initial deformation I seen on these. I will say they are thicker than some other brands of wedges but the formula for the plastic in this brand may need to be tweaked just a tad. I don't expect much life out of these. They definitely will not hold up to heavy amounts of felling, I can see that now. The barbs do work well though, and if the plastic formula gets worked out in these, it will be an excellent purchase. I may buy more but I will search around for something a bit better quality.
