We have discussed this a bunch here but the 3 finger test came up in another thread but I want to put this here because it was off the subject of the other thread.
I had emailed them explaining my understanding of the test and asking for clarification. Here is the reply I received this afternoon.
Thank you for the email! Hopefully we can clear up any confusion you have. Firstly, the goal of the three finger test isn't to understand how much pressure is needed in order to instigate a cut, instead it is to experience a sensation that (when your fingers are pressed lightly upon the primary edge) your brain tells you, 'if you move your fingers, you will be cut'. This is the sensation of a truly scary sharp edge. The easiest way for you to experience this would be to send us a knife and have Murray sharpen it for you. If you are a Knife Care and Maintenance Subscriber, send us a knife with good quality steel and Murray will sharpen the blade for you, free of charge. All we ask is that you provide return shipping, which is $15 (Priority USPS). When your sharpening your blades, what is the process? Do you finish by stropping on leather?
Thanks again for the email and feel free to contact us if you have any further questions or concerns.

Guess I have some work to do on my sharpening skill because I can always feel confident to slide my fingers along my edges. I know I need to use extremely light pressure but I have NEVER felt like I was absolutely going to get cut if I slid my skin at all. I know it wouldn't take much pressure but still I need to know what they really mean. That means I need to have a knife that they say passes the 3 finger test. You know what that means? I think I'm goint to send him a knife. Which one!??? Which of the knives that I have would I be less devistated over if it were to get lost? This is a tough one. I will think on it. The one I WANT to send him is my GB. That knife fits into two categories regarding this. It is the one I would want most to come back sharper than anything I've seen. OTOH, it's the one I would be MOST devistated if it were to get lost. Honestly, I have never had anything get "lost in the mail". Nothing important enough to remember anyway.
BTW, Jason mentioned if I were a "knife care and maintenance" sucriber. That means I at least signed up for the free 7 or 8 tips about knife maintenance Mr. Carter sends out in emails to whoever asks. So the offer of a free sharpening (except for $15 return shipping) comes to anyone who does that. Also, there's a lot of good info in the emails. I recommend getting them. They are free. I'd love to get one of his knives but they are a bit (by double at least ) out of my price affordability.
Anyway, I figured a "quote" from the web site would be good regarding this test.
