Used the Yo2 today to do a lot of work:
1) cut a sofa apart, thick fabric, foam, hemp twine, hardwood dowels, etc.
2) took down a large desk, cut wood veneer, pressboard, scored panels to snap.
Throughout the job, hit nails, staples, knots, etc. The edge was dinged and rolled, the tip blunted out, but, the performance was excellent. I didn't do any prying.
No play in lock, ergonomic grip in push, pull, reverse grip all great.
After the work, I ran the edge on a Lansky fine diamond benchstone and brought the Yo2 back to hair popping with a perfect straight edge. Gotta love the wharncliffe profile for touch up and resharpening.
I was impressed with the real-world performance.
Go use 'em, just watch the tip. They take a beating and then sharpen back up like new in a few seconds.
