Looking for Advice: EDC best angle

[BladeChemist]

So, I am aware that the "best angle" will change depending on blade geometry, thickness, blade material, heat treat, and of course intended use.

So with that in mind I have in my possession a Benchmade Infidel 3010 (non-dagger style). Way overpriced, but I love double action OTF, S30V, and this knife just looked good to me. Anyways, picture below:

Material:
S30V (58-60 HRC)

Dimensions:
3.95" blade length
0.118" blade thickness

Purpose:
Every day carry- Opening letters, packages, food items, strapping, impressing friends with an overpriced knife whose blade appears in an instant, pops hair and cuts air, then disappears just as quickly (ninja knife).

For the regrind I will be using an Edge Pro Apex with stones up to 1000 grit and 2000/6000 grit tapes to polish. (Any other advice such as stropping and getting the knife air-splitting sharp?)


So, without experimenting too much on my new toy...do you think this blade could handle a 15 degree angle? Stick with 20 degrees? Any feedback would be appreciated from you fine folks.

I've heard that a lot of knowledgeable guys won't take S30V below 15 degrees per side or 30 degrees inclusive.

For EDC I'd go no lower than 18º/side, especially with S30V.

Excellent...I was contemplating something midrange, 18º sounds good- especially since I don't feel comfortable pushing the limit just yet. Hmmm

12 per side works for me as a average with most steels, if you find the angle too low for your needs simply apply a microbevel. BM S30V also likes a high polished edge.

i'd stay at 20 on a thin blade. i don't go 15 on S30V.
