Knife Material?

Carbon steel? Coated or noncoated?

Stainless?

I do not spend much time near the sea. At the same time there is the balance that while I can take care of things decently an emergency tool might not always get the best care in those situations.

I know all the stuff folks say on the net. What has worked, or not worked, well FOR YOU PERSONALLY?

I've lived near the ocean my entire life, and carbon works fine.

If I was working on a fishing boat, or lived in the constant wet of the Pacific NW, I'd probably go stainless.

I prefer carbon over stainless but there are other factors to consider. I like the Glock knives for a cheap, lightweight, quality knife. If you dont mind the wright, the sharpened crowbars that are BK&T will be about as rugged as anything you could ask for. I have a bunch of the BK-7's and think theyre nice. Their camp knife, the BK2, is probably the most heavyduty knife I've ever seen. I keep their TacTool around for destroying things. And, finally, theyre BK11 is cute and damn handy.

For a fun and inexpensive trial, buy a carbon steel Mora (I like the OD green handle heavy Duty model). Dip the blade in boiling hot white vinegar, let it sit awhile, remove and rinse. Repeat three times, then wipe off and oil the blade. You will have a very durable and rust/stain resistant blade with a dark grey color. Worked well for me! I understand you can get a similar effect by coating the blade for awhile with yellow mustard, but I haven't tried that yet.

+1 on the Mora - I got the carbon steel version and stuck it in a potato for 3 hours (you can also use an apple or orange) , it makes "black rust"(which stops) as opposed to red rust(which keeps going) and protects the steel. I really prefer my Cold Steel SRK in Carbon V but the Mora is smaller if you need esay carry.

Mora is a great value for the money. Can't fault that thought process. As far as steel goes, the finest steel I've used in a knife is the Benchmade D2 tool steel. It's about the perfect blend of strength and hardness. The knife I bought in May and have used every day since to open boxes and many other mundane tasks is almost ready to be sharpened. I've used it to open bags of calcium chloride and salt for snow removal and there is no sign of corrosion. The second best steel I've used is 005A high carbon steel made in Seki Japan. Not as corrosion resistant as the D2, but holds an edge about the same and is easier to maintain an edge.

An option I have given many people is to have a knife designed for your needs by a competent knife maker. I have a couple prototype knives from various private cutlery designers. If you have someone in your area with the expertise, have what you want made to your specs and made to fit your hand. It would cost about the same as a high end knife, but be an heirloom piece for your kids to have when you're gone.

Well, coming from the constant wet PacificNW I'm a big fan of stainless. A stainless Mora Companion is a very handy knife, easy to touch up the edge with a diamond hone.

If you are making your own knife, it is easier to work with a carbon steel as you can heat treat it without a furnace. When you get into the "stain resistant" or high chrome/nickel steels that aren't fully stainless like D2 you get into some very nice blade properties.

For big choppers I like 5160, S7, or 52100 over any of the 1095~1055 series.

I agree with all the comments. One of my favorites is D2. When I finish the blade I put a "patina" on it by dipping it in a solution of ferric chloride. I then rub it with WD 40 and 600 grit paper. I then repeat the process after removing the oil with acetone. I keep repeating until I get the "patina" I like.
D2 contains 12% chromium and is very corrosion resistant. If I get a little rust I just repeat the "rub down". D2 makes a fine knife.
This works for all high carbon steels for me.

My absolute favourite knife is Spyderco's Sage 1. I love carbon fiber scales, though more for aesthetic reasons than anything else. Always a sucker for a pretty knife.

Why try and choose. Buy each for the pack and let time do its thing. I have many different metals and some get really used hard. Buy good quality of either and you will be happy. It's only money :)
