Hi guys,

What is the consensus and what do the experts prefer?
Should a knife that is 3 to 4 inches be 3 or 4 millimetre thick?

Do you notice any difference in slicing carving and food prep with these thicknesses?

Or is it just nitpicking?

I am hunting for some opinions as I have a choice to make for a custom.
I have these but I cant make up my mind
Bark River Liten Bror 4
Bark River kephart 3
Scookum bush tool 3

Thanks knife people.
 
I prefer the 3mm on a blade that size. It's still 3mm of hardened steel, it's not going to snap while you carve a fuzz stick.
 
Actually, IMO it depends a lot on the grind. I do convexes and Scandi's. I like 5/32" thick steel (roughly 4mm) for high flat convex grinds, and 1/8" (roughly 3mm) for Scandi's. I think most Scandi's are 3mm (roughly 1/8") thick. I really reallly like doing Scandi's on 3/32" thick steel. (Just a smidge over two mm).
 
I'd say Fiddleback is right on (as though we didn't know that). I have a convex puukko style knife that's only 0.055" thick that handles batoning with no problem, except chewing up the baton. I made a full flat grind on 1/8" stock that I wouldn't trust to that treatment.
 
All bark river knives will serve you well. I have a Bravo1 and an Aurora and both are top notch. My favourite knive at the moment though is still my F1. Check it out you won't be disappointed. In terms of thichness I think the edge geometry plays a much more important role. The F1 is the best I've handled for carving.
