I didn't get a SAR4, having just purchased the less practical but way cool HG55LE. How would you rate it against the Bark River Bravo-1 (if you have one of those)?
That SFNO LE looks great. <img src="/ubbthreads/images/graemlins/thumbup.gif" alt="" />
I did have a Bravo-1 Vic but sold it because I found the spine ramp to get in the way when I wanted to use certain "grips" on the knife which involve me putting my thumb on the spine. What I should have done was ordered one without this feature....there were some on Knivesshipfree when I got my Bravo and I deliberated which way to go at the time....however they did'nt last that long and when I sold my original Bravo knife there were none left.
Aside from this issue I liked the Bravo 1 a lot and it is a Benchmark knife for EDC Woodcraft type use. The SAR4 is a different knife altogether in terms of weight and size. Much more a BATAC sized knife which I believe you have owned....but without the very thick and heavy handle I had on the BATAC LE which came with a .25 thick blade and handle. At .20 thickness though the SAR4 is very close to a BATAC CG. This size of knife dwarfs a Bravo 1 and even a RMD can make a Bravo 1 feel a "lite" option.
My RMD however was also part of the reason for selling the Bravo 1. I found the RMD to have just that extra little weight and ability on certain tasks and felt I would not carry the Bravo 1 if I could pick up my RMD.
The SAR4 though is really like the next level of knife up from the RMD weight without hitting that obvious level of weight which you would categorise as a "chopping" knife. Although that being said....if you hold the SAR4 by the end of the grip to give more leverage for chopping it is really quite suprising as to how well it can cope at this task.
Talking now with hindsight knowledge that an Infi S5 LE will be made and which I have ordered....I would now categorise this knife as the closest knife in Infi to a Bushcrafter knife....but prior to learning of this....the SAR4 was perhaps the nearest for me. I have not had the old models however such as a Basic 5 or an old Badger III....which might be a closer comparison... although I doubt they would eclipse a S5 LE for ability.
