I happened to get a set of old Cutco kitchen knives to sharpen for a good friend. Model no.'s 21 thru 25. The knives were in pretty bad shape. Looked like they hadn’t been used in 20 years and that the previous owner had freehand ground the primary bevels back to thin the edges. A few were badly dinged and all the handles were rough. Probably had been soaked in a dishwasher. Cutco currently uses a thermoplastic handle material. These seemed to be a dense hardwood - maybe rosewood. Clearly not plastic.
The knives were in bad enough condition that I decided they needed a complete going over. I took to the buffing wheel with 240, 300 & 400 grit compound wheels to clean up the very rough grind marks and stains. I mangled one of the handles by slipping against the 240 wheel. Rats. Spent about twenty minutes trying to make that look normal, but it looks pretty good now. I polished up the handles using “Scratchless” white compound. Not bad.
I then took to the Wicked Edge, deciding to hit each knife with an 18 dps main bevel polished down to 3 micron film. I then put on a 1000-grit microbevel for a toothy edge. The 4-3/4" boning knife got an 800-grit microbevel.
Interesting tidbits… My friend’s uncle had modified each of the knives by thinning the blades behind the bevel lines. As crude as it looked, he was pretty accurate and my 18-dps bevels only exceeded 1mm in width at a very few points. Each of the five blades showed evidence of having been sharpened with a steel. No sign of ever having touched a stone or belt. I’ll have to ask if the gent was a meat cutter.
So I went online looking for info regarding these knives and came across a youtube Cutco video where they teach their reps how to sharpen their straight knives and serrated knives. Basically, they have a copy of a Spyderco SharpMaker, but add a feature to their triangle stones to handle their “Double D” serrations. One side of the triangles is grooved to match the serrations. Pretty crude, highly unsophisticated teaching session. Here’s the video link. Jump forward to about 12:30 to find the serration demo. Apparently they use only one type of serration.

Imagine what you would be thinking if you were in this guy’s audience. Gaak!!
