I have owned my F1 for about a year and i have been very pleased with the knife.
It doesn't see as much use as my WS Woodlore (my preferred knife for most outdoor activity) but i have found it a pleasure to use and certainly lives up to it's reputation as a good all round bushcraft knife.
The VG10 blade is rust and stain resistant and holds an edge well.
The spine is square and casts an amazing shower of sparks from a firesteel.
I don't have particularly large hands but one niggle with the F1 is that i find the handle a little slim in profile, especially for extended carving sessions.
The VG10 stainless and Thermorun handle make this an easy knife to clean after game / fish preparation and the handle remains grippy even when wet.
The H1 on paper would seem to be quite similar to the F1 and this is why i found it hard to justify buying one.
When i did eventaully get one quite recently ,i discovered the H1 has a character all of it's own.
Both are the same overall length, feature a protruding tang and use the same triple laminated VG10 steel.
The H1 has a much fuller handle and the softer Kraton is easier on the hand and slightly grippier than the F1.
The F1 blade is fairly thick but the H1 is even thicker but it still slices surprisingly well, even coping with finely slicing tomatoes.
Neither knife is particularly suited to chopping but both work well with a batton.
Both of these came with the "dangler" sheaths.
I wasn't very impressed with either, the H1 has a liner and i find it makes it quite difficult to insert the knife.
I do quite like the idea of the dangler sheath when wearing a back pack.
I have made replacement sheath for both with firsteel holders as both work very well with firesteels.

I can honestly say the H1 was a huge surprise.
I never imagined it would be better than the F1 but it is and i can see this one being used a lot.
For me, my new H1 makes my F1 redundant.
If your in the market for a new knife and thinking about an F1 do yourself a favour and check out the H1 as well.
