Spyderco Forums

I have the reverse tanto in 3V. Definitely wasn't sharp from the factory, but it didn't take much work to fix that. I did install the automatic pivot and the spring pushes the blade noticeably off-center, but not so badly that there's blade rub (or even close). It's an interesting knife, with a ...

Nope. Have one (the USN forum Endura). Almost never carry it and changing the steel won't change that.

All my Spyderco knives are self sharpening 'cause I sharpen them myself.

I'm not really the person to help you with this, but here's a thought: seems to me that no counterfeit is going to have an H1 blade, so stick the knife blade in a glass of salt water and see what happens

It was on the 2023 discontinued list, so three years ago.

Tip is a form of reward for outstanding, not doo doo service. When service is bad, or no existent no TIP.

The message "heard" by the server when you don't tip is: "cheap SOB." The correct response to poor service is ask to speak with the manager. Tell them why you're unhappy.

Not with the round one, but yes with the triangle or the slip.

@RustyIron: YES! Exactly. And you can use your SE knife, particularly one with some belly and pointy serrations, to "cut" the tape on your packages the same way. Push the serrations through the tape, creating a "dotted line" and the tape will part without gumming up your edge.

I prefer books where authors who should know better write about Glocks and modern revolvers with (manual) safeties.

Take a look at a tape dispenser, any kind - scotch tape, packing tape, whatever. Ask yourself why they don't use a plain edge to cut the tape & why you never need to clean tape residue from the cutter?

But does it really make for an informed decision? Harder is just that, harder. Not necessarily a more suitable heat treat and not necessarily better performing at any metric.

That's nice. What's its pedigree?

Bone conduction headphones are great, especially if you wear hearing aids, like I do.

K390, 15V, Rex 121 -- love me some high carbide volume steels. CPM 3V, as well. But also, at the other end of the edge retention spectrum, good old O1.


Sounds like you have alot of experience with these steels, how would you compare each to K390? That is the only one I have experience with ...

Your thought is correct. There are electric sharpeners that work reasonably well, but that ain't one of them.

Glad I moved quick when I got the email.

I'll have to ask the mice in my basement and my garage if they have any suggestions.

Very cool. How about a picture of the knife itself, for our edification?
