Edge Retention Choice

[kreole]

Does magnacut do everything H1 does but better?

Nope. Not as tough (no carbides and is run softer) and not as rust resistant

So you're saying your Para 3 was in fact NOT sharp 3 months ago now? Sorry, I'm just trying to fully understand here.

I’m saying that I thought it was sharp because it popped some hairs from my arm and 3 months later it struggled through a zip tie. Has me thinking I want a steeper and tougher edge. Also strongly planning to revisit my sharpening knowledge.

This would be a cheaper solution if it's the case too, though new knife purchases are always more fun

Before this thread I did not know that an edge can dull from sitting just from slight corrosion, or at least never thought hard enough about that being a possibility.

I have not owned one yet but i've heard that rex 121 is supposed to be crazy about retention. Supposedly you don't have to sharpen this hardly ever.

Never skip an opportunity to overthink the need for a new knife or skip the chance to buy it.

My CPM M4 knives do this. They will shave like a mach 3 razor right after I touch them up, I have had them lose that just sitting a few months in my knife drawer. The working edge goes forever though.

Something H2 Serrated

 

[Red Leader]

Eric/Sal have stated that the H1 Jumpmaster SE is the highest edge retention they have ever tested, and there has been a lot of discussion around why, including the work hardening theory, but I am not sure if it has ever been fully tested or explained.

Rex-121 is your answer at least for plain edge, but be aware that it may not come with the edge you want, requiring you to sharpen right off the bat. That was my experience with my Sage 5.

Here are the top stainless steels from a corrosion resistance perspective (at least the ones I copied from Larrin - this is his data):

Steel	Toughness	Edge Retention	Corrosion Resistance
LC200N	8.5	3	10
Magnacut	7	5	9.5
S110V	3	8	9
M390/20CV/204P	3.5	6.5	9

S110V has possibly the best combination of rust resistance and edge holding, but requires special stones to sharpen it (diamond coated or CBN). If it will be used very little, I would probably go with Magnacut.

Thank you Larrin for your work on this - it's great stuff!

I have a waterway that is just phenomenal. I use it for all kinds of stuff. Ide suggest it for a fixie.

I use my Waterway for food prep. It always makes me smile.

I think it would be pretty cool to have a fully serrated one. Would make me smile as well.

Here’s one for you steel junkies. Edge retention above all else. This knife will rarely cut anything, it’s an emergency blade only but occasionally maybe a quick zip tie or open a package. I don’t want to sharpen this knife. Ever. If needs be it will be sent in to Golden for sharpening. What do I want? Thanks to all.

Get the blade you want in what ever steel - doesn't matter what it is. Just carry carry a small utility knife to cut "the occasional zip tie" etc.

I have several SD/ER knives that don't cut anything. I carry a small EDC utility knife for those tasks.

 

[RPZIP]

I’ve been thinking of getting a serrated blade for the ready knife. Cuts may not be pretty but they will cut for sure.

I have several Spyderco and Cold Steel SD/ER knives. They will all cut like blazes even after decades of ownership. But they don't get use for anything.

S110V can be sharpened just fine on the brown ceramics. I've been doing it for years. Re-profiling or major edge damage would certainly benefit from diamonds or CBN, though.
