Bought myself an F1 for my birthday. Delivered today. Smaller than I expected. Blade about 3/4 inch shorter than my 1st gen CS Master Hunter (which I like a lot) that I have had for quite a while (picked it up as a 2nd blem at a Puyallup WAC show maybe 20 years ago?). The tang of the knife extends out of the grips with a short striking pommel, but the lanyard hole is in the grips. Blade also seems a bit thicker, maybe the same, but does not taper in thickness to the point near as fast as the CS MH even accounting for the shorter length; the MH starts to taper to the point about an inch from the hilt, whereas the F1 doesn't start to taper until about two thirds of the way to the point, probably making it a stronger blade if you just go by thickness (not to mention that my CS MH is high carbon steel and the F1 is laminated VG10 - today you can get a MH with laminated VG1, which reportedly is not as good as VG10). They both have the same small notch choil just in front of the finger guard, but the F1 choil is deeper. The rubber grips are much thinner than the MH, the F1 grips about 3/8" shorter with the finger guard about a third of the height of the MH. The grips of the MH seem a tad softer and have slight molded serrations top and bottom where the F1 is smooth top and bottom, with the checkering on the sides less pronounced than the MH - still, it feels good in my hands, although noticeably smaller and thinner (it just barely fits in my somewhat large hands whereas the MH has a bit of room to spare). The grind and shape of the blades is very similar - the MH has a full flat grind, the F1 a flat grind with a convex edge with the laminate line showing right at where the convex edge starts (you can also barely see the laminate line in the spine if you look close). The F1 is almost an ounce lighter than the CS MH. They both balance about the same - about an inch behind the finger guard. Out of the box the knife is very sharp - what I call cutting grass sharp; a thin loose light blade (not a stem, a blade) of tall grass, standing free, not held, will be cut with this blade with a single swing. IMO, if a blade can cut something like a blade of grass that doesn't give it any resistance (that will just as soon bend as be cut), then that is pretty sharp. And yes, it will shave the hairs on my arm but I would not want to shave my face with it. In short, the F1 seems like a slightly smaller and more 'subtle' version of the CS Master Hunter, but with what seems to me to be a better design and execution. I have yet to use it in the field, but I think it will be a better knife. The Zytel sheath? Not very good; the blade will drop free of it if shaken and the strap is not fastened, even though there is a very slight lock detent.
