I have been unable to wear out my Super tool as of yet so have not tried the newer ones.
I was skeptical of the Mora’s at first but just love them after using them for a while. I have the Craftsman in both carbon and Triflex carbon and really like them a lot. I enjoy the look and feel of wood for handles so I have maybe 6-8 with the wood on them but had to work on these handles before I got them where I liked them. The ones with red paint got sanded to remove the paint and then all of them got flamed with a torch, sanded and soaked in linseed oil and turpentine for a week or so. This gives them a real nice look and feel to them. The gap between the blades and handles I fill with melted beeswax to make a removable food grade seal. This seams to keep the nasties at bay quite nicely.
I find the #1260 so useful that I wear it as a neck knife just about all the time. I cut down the sheath to fit the knife and heat welded the bottom closed then redrilled a drain hole. A split ring and a leather thong made it into a great little companion knife.
I generally prefer carbon steel so have not tried the stainless ones yet. I might try it since my carbon Craftsman does not like whitewater rafting as much as I do.
When you talk about splitting wood with your Mora I assume you are using a baton with it, which is less than ideal, but very doable.
I have not tried the # 510 yet but do have some time with 13 other Mora’s which all hold up way above their pay grade.
