I got the Outdoorsman Series Large Sunfish in natural bone, because it was 10 bucks and elephant toenails are neat. It wound up supplanting my Opinel Garden Knife as my EDC, because it was ludicrously sharp, a joy to handle, and looked interesting. The short length and absurd width really fit my hand and working style. The pull and snap were unreal - super smooth and and almost aggressively positive.
It was a bit gritty, so I blasted it out with WD-40, and then lubed with dry lube. Apparently the grit was the only thing holding it together - it developed some serious blade-play on the large blade. It was reluctantly retired, and I've asked, pretty please, for a GEC All-Steel Sunfish to replace it on my berfday.
Just today I found a youtube video showing how to tighten old slip joints with a bench vice and a ball-peen hammer. It worked - too well. The super-smooth action is now tight at the 90º point of the arc, tho it does snap open and closed without drama.
Another consequence is that the nice, shiny finish on the bolsters was dinged, and the pin now shows through. It needed some rehab with a round of metal sandpaper headed from fine to 800 to 1500 to 2000 grit and a final, furious rub with a Scotchbrite pad. It's now got a nice satin brushed-brass look that I replicated on the other end.
It's a lot less refined looking than the original, but it suits the natural bone scales better, I think. It needs a bit more time with the Scotchbrite, and some more exercise opening and closing, but not bad for a kickin' around knife while I wait for the GEC.
