Blades that have geometry comparable to CRK's

[SteelStickler]

I love the slicing geometry of my umnumzaan. To keep it short and sweet, what folding blades have you encountered with similarly thin blade thickness' behind the edge?

 

[Bugout Bill]

The Umnumzaan doesn't have all that thin of an edge compared to alot of other knives (i.e. Spyderco).

I actually had to reprofile my Umnumzaan, I must say that it cuts much better now.

In comparison to other knives of similar blade thickness, CRK does a pretty good job. Interestingly, it actually thins out even more above the factory bevels--so it's geometry should actually improve with sharpening (to a certain point).

Spyderco's Caly 3 and 3.5 get pretty thin behind the edge.

I had to spend considerable time sharpening for any of my CRKs to be competent slicers.

MEASUREMENTS OF COMMON KNIVES BEHIND THE EDGE.
These are my measurements, using digital calipers. They are not top-of-the-line digital calipers, but they are accurate enough for our purposes.

ALL MEASUREMENTS ARE INCHES

Spyderco Endura4 plain edge 0.023"
Spyderco Delica4 plain edge 0.026"
Spyderco Para2 S30V .026"
Spyderco Lightweight manix flat ground BD-1 plain edge 0.027"
Spyderco Millie M390 0.0235"
Spyderco Manix XL 0.0295"
Sebenza, Large 0.021"
Umnumzaan 0.023"
ESEE Laser Strike 0.049"
SRKW Howling Rat Little Mischief 0.0485"
ESEE 3 0.029"
BUSSE CABS 0.023"
Spyderco Elmax mule stock 0.0245"
Strider SMF in CPM154 0.036"
SRKW Chopweiler 0.049"
BUSSE Basic 4 0.0315"

Most of my customs go below 0.019685 (0.5mm) behind the edge, but I cant measure that accurately beyond 0.5mm since I have manual calipers.

+1 to this. The E10 I sometimes carry has surprised me by being one of the best-cutting knives I've owned. Thin at the spine and then hollow ground really thin to the edge, the damn thing cuts like a laser beam.

let me rephrase - thickness behind the edge! i'm fine reprofiling my own knives, have for a while. I just notice how efficient the blade shape is and I'm wondering what blades have nice hollow grinds similar to CRK. Marthinus - that's great info, really appreciate it.

Glad I could help. The only knives I have experienced that are ground thinner than my Sebenza are from handmade and custom knives such as Burger, Des Horn, Andre Thorburn, Andre van Heerden, John Arnold and Herucus Blomerus.

I know makers such as Gavko, Dan Keffler and cKc knives do really thin high performance grinds as well and I like their products.

Have you considered the Spyderco Nilakka? Not hollow ground, but about as slicey as one can get in a production knife.

I definitely prefer my knives to be on the thinner side behind the edge. It's rare that I get a new knife, or look at a knife, and would prefer a thicker edge. In general, at the spine, I prefer my knives to be somewhere between 1/8 - 3/16". 5/32" is just about perfect to give me "what if" confidence. But with CRK's HT being a little softer it is also more durable than other similar knives.
My knives that are as thin behind the edge as my Sebenzas (or comparable) are all Fixed blades. Fiddleback Forge, TFK Rubicon, Boye Basic 3, SYKCO MAXX 375, ESEE3.

I appreciate the ideas behind both Flat and hollow ground blades. None of the hollow ground knives I've had are as well done as CRK though... well actually I did have a custom Burger Exkelibur for a short while that was reeeeLly nicely hollow ground.

The last few full flat ground Strider SnGs I've bought have had perfect, on the "slicier" side, grinds.

One of my newest knives, a Phil Rose PSK 2, came with a crazy thick edge. My calipers are the crappiest ever so I can't get the best measurement but I'd say that it is ~1/16" behind the edge! I kinda wanted to immediately return it. To add insult to injury it also has the strider thing going on with the edge where it starts out at 40degs at the sharpening choil and twists to ~45degs at the tip. But I'm here to learn. How do I know if I don't like it if I don't actually try? I've re profiled the edge to 40 inclusive with a very broad 30deg back bevel just for piece of mind and I've carried and used it every day for the last few weeks. It has done everything I've asked of it well. Some of the testing I've done has been lack luster but they are not things I do regularly. Handle comfort is also VERY important, especially with "white knuckle" cutting. It has the most comfy handle I've ever used. Cutting hard plastic does come with much resistance but the handle really makes it more doable as does "chest cutting." I put it up against knives with very thin edges and they did do certain tasks with less effort however equal, but different, fatigue because of the handles. Everything else I like in a knife is "there" and it's become a favorite for sure.

Yep... SnG FFG.

Buck 110 (BassPro CPM154), Cabella's Griptilian in D2 are great slicers.

My E10 has basically kicked all of my CRK's out of my EDC Rotation. If I want a lean slicer that's what I go for. I don't have calipers but would love to know how thin that one is behind the edge.
