I had a couple of these in front of the house i used to own 35 years ago. You didn't even want to look at those Locusts out of fear of those spikes. My old boss used to say they reminded him of Vietnam.Locust is great wood. The older growth trees were covered in 3-4" daggers. If it wasn't in a bulldozer pile with them rubbed off I'd pass. I've seen several thorns go through a boot, it's not pretty.
Never knew exactly what type of locusts they were. All the other many locusts around here are thornless honey locusts.
