So I've set up my new T8, I have the hand tool kit and have sharpened a few cheapo Sam's club knives and tried my hand at my 20 yr old Henckels. The Henckels have been dull for a long time. I used the suggested 15 degree (30 inclusive) and it took a long time to get any burr. I used the wheel at 1000 grit. Are these knives made from steel that is generally harder? Any pointers on sharpening these in general?
thanks
They're not particularly hard steel... it is not unexpected that 20 year old knives sharpened at 15 deg. would take a bit of time... (I think older Henckels usually came at around 20 deg.)... especially if you did them with the stone graded fine. I'm guessing you now have a noticeably wider bevel? So, two things to "overcome"... the new angle, and probably very dull knives.
Only real suggestion would be to do some of the initial work with the stone graded coarse, to speed things up. If you mark a knife bevel with a Sharpie marker, and you want to sharpen at a specific angle, and notice that you're removing marker at the top of the bevel (away from the edge), that's a good indication to start with the coarser setting. Then when you establish a good bevel, you can switch to the finer grit, if desired, to finish the edge.
BTW, nothing wrong with them at 15° (if they were originally higher)... should be fine... (if not you can always put a small microbevel on at a higher angle).
Does the stone grader accelerate wear on the stone? I was unclear on this point or if it had been measured in any way.
Thanks for the reply. I have a lot to learn. The videos make using this thing soooo easy. I can see why there are so many for sale used with little use.
