The F1 is quite a heavy knife, not something for neck carry (unless of course you have no neck, enter Mr Universe), the steel is a high quality laminate, it is reasonably low maintanence and once you get used to sharpening the convex grind it is quite easy to keep shaving sharp.
One of the guys mentioned that it casts one of the best showers of sparks on a firesteel from the spine that you will get. If you don't like the handle rehandle it or get one of the blade blanks and make your own handle and sheath.
I would suggest handling one before you buy, try and get to a meet at some stage the chances are that someone there will have one. As a couple of the others have mentioned knife choice is a very personal thing and even though Joe doesn't personally like it he can see that it has a very good rep.
Neil1's F1 has been slightly reprofiled and carves wood a lot better than the original.
