When I picked up this Reiff F4 back in October, I looked for a review here but didn't see one. So I bought it based on a few things I was eeing with my own eyes and hoped for good results in use over time.

Overall it is 9 inches, with a 4 inch blade made of 5/32 CPM 3V steel with a high saber grind, and has 3 dimensionally contoured G10 handle scales, and comes with a really solid kydex sheath.

It is the size knife I wanted for field craft demonstrations. I like the blade profile, grind geometry, thickness, and that the front side of the sharpening choil angles forward so it won't trap small cordage. I really like the handle size and ergonomics, and LOVE that the forward end of the handle scales wrap down around the forefinger and create a nice wide guard to push against rather than just using the thickness of the blade stock as a guard. I loath integral guards on working knives.

I also like how the sheath is set up somewhat like the Mora Companion sheath so that I can quickly and easily relocate the sheath from my belt to my pocket, or a cord around my neck to deal with changes in terrain types without having to partially undress in the field to do so. So far the clip is holding up well.

It had been so long since I had carried a sheath with a firesteel loop I think I have given most of those type ferro rods away to students and borrowed one of my daughter's ferro rods for the first demos, and ordered a new Exotac fireROD for it later.

I have a presentation area at work where I do different skills presentations

The first demo was on a dry day, so I did a version of a twp-stick heartboard made of Yucca stalks and feather sticks with a ferro rod. No pictures of it, but it cut the yucca stalks like they were hot butter as pretty much any sharp knife will. It handled nicely when making the feather sticks, it came with an extremely sharp edge.

The next was on a day of off and on light rain, so I did a presentation on pine knots, why they work so well in the rain, how to distinguish between pine knots and one of their lookalikes here, Hemlock knots, that are not at all useful for firelighting in wet conditions

I showed them how they look and smell very different on the inside, even if sometimes they can look very similar on the outside. The F4 had no issues with being batonned through the pine knots. And handled really well when whitling pitchwood shavings as well.

And I showed them how having a dedicated striker was not only a bit safer for striking a ferro rod when cold and having fatigued hands, it could also come in handy for sraping easily ignited pitchwood fuzz from the pine knots, preserving the knife's edge for other uses.

And then I showed them how effective pitchwood is at helping to achieving sustained fire here in our temperate rain forest, with them seeing all the steam from the moisture being cooked out of the damp wood by the heat of the hot-burning hydrophobic material.

I've done a couple of other classes with the f4 I didn't photograph. and with what I have seen and felt out of it I am very well pleased with it as a fieldcraft / bushcraft knife. It's one of my favorite knife aquisitions so far, and that's saying something. I like it better that several handmade bushcraft knives I've paid more for.

Excellent review!

I have a Reiff F6 and very briefly had a F4 with green scales.. I couldn't get past the longer handle, shorter blade visual. My OCD was killing me on it. I also thought that the scales were too contoured/coke bottle-ish compared to the F6. Plus I hate G10....despise it. I especially despise green G10. I believe that mine was an older one, maybe even an early prototype. The new ones may have less contour?

With that said......I was just going to buy another one with black G10 scales! Seriously, I wanted to give the design a fair shake. A surprise Gossman Polaris popped up that took all of my funny money for now, so the F4 is on the backburner. I may revisit it someday!

Thanks for sharing!
 
👍👍. Great knives. Looks like some fun was had during the demo as well.
I think they are too. May try and F6 later but that's more than I usually carry for a belt knife for field crafts. I'm more drawn to 5 inch blades than any other sze really. And yeah, I try to make my presentations fun, thanks!

Thank you!

Yeah, still have some issues with blades being too disproportionally shorter than the handle, though I've become more okay with it over the years. A lot of years holding Fiddlebacks got me used to it I guess. I used to not be able to like a knife on which the handle was longer than the blade any at all, they had to at least be equal lengths. and I preferred the blade at least a little longer than the handle. I would love to see a Reiff F5 with this same handle and a 5 inch blade the same blade height as this one, just stretched out to 5 inches. With maybe a slight clip and a bit of a swedge just to be a little different...more of a filedcraft knife than a bushcraft knife.

And I get that about G10, black is one of the few colors of G10 I do like. For lighter colors I much prefer micarta. It seems easier to clean up. I can't say abou the older ones, or the protos, but the contours on this one aren't exagerated any, the handle is comfortable in every hold I've used it in.

I'm sure the Gossman will serve you well!

Thanks for this. I'm surprised Reiff doesn't get more attention, and that there aren't more reviews out there. I acquired an R4 recently as well, but we are in the depths of winter still, with several feet of snow on the ground (and a lot more in the mountains above us) so it will be a bit before I can put it to much use.

Overall it seems like a very solidly built knife and the sheath design/fit are excellent. I have some concerns about the long-term durability of the belt clip, but time will tell.

Looking forward to seeing more in this thread, and I'll contribute once I've been able to spend more field time with the knife.

Sorry for the long delay, work has been consuming, and we're getting ready to go on vacation soon , so lots of preps going on.

I agree, I was surprised there wasn't more info on them when I looked into them before buying this one. Just looking at all the details of the knife they've clearly got some folks with a lot of experience with knives in the field providing input for the designs. They are very well thought out and very well executed in my opinion. Though the belt clip is still a bit of a question mark for me as well. Though the few times I've forgotten to take it off before getting in the car , and it got stretched out due to the seatbelt buckle, it has so far always gone back into shape and hasn't been stretched to breaking yet.

I'll have more on it later on after vacation.
That is a good looking, functional knife, thanks for sharing!
Thanks! Glad you enjoyed the post!
Thanx for your thoughts!!!!
Been a while since you've posted a review......I miss your thorough, expansive reviews!!!!
Great pics too!!
Thanks man!! Yeah, life got pretty crazy for a while and my finances went through h*ll and I had to start all over again, but I think I'm finally getting it back together. I have more knives I've bought I hope to get to review later!!
 
I just discovered Reiff Knives and like what I see of them. I have a CPK Basic 5 Field Knife on the way (5 1/2” blade) and would love to see a comparison with a Reiff F6 Leuku. They’re both in CPM 3V.

Anyone here have both?

I think they are too. May try and F6 later but that's more than I usually carry for a belt knife for field crafts. I'm more drawn to 5 inch blades than any other sze really.

A Reiff F5 would get my money right away. And be a better comparison to a CPK Basic 5 Field Knife.
