I carried the Juice S2 for quite some time and I loved it. I stopped carrying it simply because I upgraded to LM Wave. If you want pliers but can't bring yourself to carry that 1/2 lb steel brick called Wave, the Juice would be your best option.
The closest comparison to the SAK line is Deluxe Tinker, because this SAK model has pliers and scissors, and it has the exact same weight (4.4 Oz). If your day revolves more around cutting tasks, then the Deluxe Tinker with its two blades is for you. But if you are more involved in fixing mechanical stuff and playing with wires and electrical cables (like I was), the beefy LM pliers are indispensable.
Missing from the SAK Deluxe Tinker (compared to the Juice):
- Hard wire cutter (both have wire cutters, only the Juice has hard wire cutter)
- Small (eyeglass) flat screwdriver
Missing from the LM Juice (compared to the Deluxe Tinker):
- Awl
- Hook
- Wire stripper
- Short extra knife
While the knife on the Juice is narrow and puny, it's long enough and it cuts just fine. The pliers on the Deluxe Tinker is not even in the same league as the Juice. I have used the pliers on the Juice to turn gas valves and the occasional hex bolt; I can't picture doing it with the Deluxe Tinker.
About quality: LM tools are not quite up to SAK in terms of finish; probably done so on purpose to save cost. In some cases, LM tools are literally rough around the edges. But, this does not detract from their function. If you like polished finish with no rough edge whatsoever, then SAK is for you. If you don't mind bead blast finish with occasional rough / non rounded corners, then LM will be just fine.
