I would love to see a close up picture of a tire lug that you ran the fine blades of the siping tool through

Fascinating.  Never knew this product existed.  Good job with the video.  I wish you success and a happy new year.

Been siping and grooving for at least 20 years. I just use a couple Ideal grooving irons. It’s definitely a lost art form. You can lots more miles out of your tires especially if you run muds. The greatest satisfaction is when they work 10 times better and they are still in balance if you’re good!!
