I got this blade years ago and found out it had a warped blade.
Finally, found a set of warped scales that matched the blade perfectly.
However, the spine miked out at .1614 and the width is .897, that worked out to 10.3 bevel angle.
2 layers of tape and the nose and toe were turning to foil. Digging through my junk drawer I found a cheap compass and cut off the tubular shafts and opened them to slide over the blade. A layer of tape to hold the 2 pieces together and off to the stones with a 17.9 bevel angle. Much better! While not a perfect edge, it did give an adequate shave and I saved the fake frameback for future touchups.
