I’ve been using the 1500 diamond for my SG2 steak knives and been happy with the performance. I wouldn’t recommend ceramic for steel that hard though.

I’m looking forward to seeing the results of these measurements. One thing that I would love to see (in addition) is the material removal rate.

Todd Simpson replied to the topic wusthoff in the forum Thoughts/Theories/Science Related to Sharpening 5 years, 8 months ago
I have a few Wusthof “grand prix” kitchen knives that I bought at least 20 years ago. They are nice knives, easy to sharpen and respond well to the steel. They’ve been through the dishwasher a thousand times.
The only problem is that huge bolster eventually needs to be thinned if you want to avoid a recurve. If I was replacing them, I would bu…[Read more]

I understand the use of this when a new account is created, but I’m not seeing why it is necessary when existing users login. I had to complete at least 6 of these to login just to make this comment. Honestly, these things discourage me from making a contribution when I browse here.

Todd Simpson replied to the topic Any chemists around here? Isopropanyl alcohol in the forum Suggestion Box 6 years, 9 months ago
Methanol, Ethanol and Iso-propyl Alcohol (IPA) have fairly similar cleaning performance. IPA is preferred because it evaporates more slowly than methanol and ethanol and doesn’t have the regulatory issues of ethanol. It’s available in high purity for a relatively low cost.
Acetone is a stronger solvent, in that it will dissolve a wider range o…[Read more]
