Hock blade issue |

I have been using Hock plane blades over the past 20 years with no issues. I have a #3 that I picked up a few years ago, but set it aside and let it collect dust. A few weeks back, decided to get it in working order. Blade was pitted pretty bad so I ordered a Hock blade for it. Cleaned up the back and honed the edge. I did notice that while I was able to get it sharp, it was not getting quite as sharp as I like. Tested it on some scrap wood. First pass worked, then subsequent passes, nothing but scrapped dust. Inspected the edge and it was crumbled.
I sharpened it again, but the edge crumbled.
Ground the bevel on the Tormek and honed the edge as normal. Again, the same problem.
Did a little more work on the back, and sharpened again. I will say that the blade was very flat to begin with so that did not take much effort.
Again, the same problem.
Last thing I tried last night was grinding away some material on a CBN wheel. Going into the shop today to focus on that plane and see if I can get to the point of good steel on the blade. I have probably removed a touch more than 1/32” of the edge at this point. I have had this problem with a 1-1/2” Ray Iles chisel before, but never had this issue with Hock irons.
Whats the chances that it is only the edge of the steel versus the entire blade having a bad steel/heat treatment?

Some years ago I switched from a Delta Unisaw to a SawStop Professional saw, and have never regretted making ti (expensive) switch. Love the SawStop. I've tripped the brake about three times. Cost of a new blade and a cartridge about $150, but that amount wouldn't even get you past the front desk at the emergency ward.
Yesterday when ripping a short length of walnut, the saw decided to lower the blade below the table, without cutting power to the blade. Retrieved the piece I'd been ripping, tried to complete the cut, and had the same problem. Then I tried just turning on power but not running any material into the blade, and the blade slowly lowered itself below the table. Tried to raise it with the elevation whee., and the control refused to raise. Lowered the control and then raised it and it brought the blade back up to full height. Tried it again, same thing. It took the blade about 30 to 40 seconds to lower beneath the table top. I then submitted a problem report to Saw Stop, and received a reply that they'd get back to me as soon as they could. Waiting for a reply, just for grins I decided to remove the cartridge and then reseat it. Sure enough, quick no-cost fix, let the bsaw running for several minutes, and it remained at its set height. Forr a test I ran a 4 foot length of particle board through the saw, making half a dozen cuts, and the blade remained at the set height I repplied to SawStop's response to my initial report, describing what I'd done, letting them know the case number could now be closed. And now I know what to try if I ever encounter this problem again.
