Glad the ARC is sorted out. I hope you get a great many years from it. I personally have got to have follow ups on that Magnacut blade please.
Personally I think Magnacut is just the fad/hype right now. Like S30v was in 2008. It is just another blade steel, and it is the new hot thing. Keep any quality knife maintained and even 420hc and 154cm will do a similar job.
My view is that most of us don't notice anything about blade steel, unless it is cr@p steel that is never sharp. We generally open Amazon boxes and other daily stuff with our MTs, where all of these blade parameters don't really matter. Of course, there are exceptions and some folks really use their MT blades on the job site or whatever. [I somewhat envy those people!]. But a roofer cutting shingles all day is not going to use an ARC. He will use a $20 box cutter with carbide blades.
I really want an ARC but I'll get one in a few years on the second hand market when somebody pawns theirs or loses it to the TSA. Meanwhile, I'm eagerly awaiting BF's real world, hard use on the farm report on all of his new tools.

One major positive of the ARC is that all tools are outside-opening. This is relatively rare in the Leatherman bloodline. Others include the Skeletool, MUT and P2/P4 if I am right about that. And the outside-opening architecture gives you a smooth gripping surface when using the pliers. This is one (of many) areas where the Swisstool and Spirit have long excelled. And where the ST300 and Rebar have fallen short IMO. Not a deal breaker, because I love those latter 2 as well (the Rebar is in my top 2 for EDC), but inside-opening is somewhat of a poor design element. In theory, inside-opening like the ST300 might keep the tools clean if you throw your closed MT in the mud, but that's not something most of us do very often.(Image removed from quote.)
This is off topic, but a box cutter/utility knife Challenge would be a groovy thing to do some time.
