M390 is a recognized blade steel with a generally good reception in the marketplace and with end users. Sleipner is a bit of an unknown but, appears to be a good blade steel as well with properties similar to D2 leaning a little towards good Carbon tool steels.
I find I need fixed blades to be more than 3" and 5" or less in cutting edge. I prefer flat grinds but, a high saber grind works well too especially with a false edge on top. I want a knife of high quality that won't break the bank. A nice leather sheath never hurts either!
How do the M4 and M5 compare to each other? Is the M4 "pocketable"? How do both carry on the belt in everyday use (sitting in a car seat or tractor seat, sitting on a bench, getting hung up in brush, etc.)?
I need some corrosion resistance but, nothing too extreme since I generally don't have issues with carbon steel knives. I need something a normal human can sharpen with normal sharpening stones (no CPM super steels please!).
I need a knife that can be used in pinch for meals (cutting cheese, vegetables, meat, etc.), will cut baler twine and poly rope, along with more mundane cutting chores (cardboard boxes, packaging, branches/twigs, etc.).
The Lion Steel fixed blades seem to have a very high level of fit and finish with a top quality leather sheath so, I am looking seriously at them. I would be tempted by an M4 in Santos wood but, they aren't available apparently.
TIA,
Sid
