Garageboy,
OK - the calypso jr is a limited run of 1000. meaning, even if you wanted to, you won't be able to get it once they run out. that should be a big reason to get em.
delica and native, you can always get later.
tell you what, get the new grey calypso jr plain edge, and if you don't like it, I'll take it off you (email me off line and we can discuss details). get it from new grahams. they got them at $40 + some change only.
i don't believe you will be disappointed in the performance of that full flat grind. the swedges on the native just don't speak out to me, not on a package that size.
FULL FLAT GRIND ROCKS! trust me.
S30V is a better steel, but honestly, most people can't tell the difference during field use. I have used both spyderco VG10 and buck paul bos heat-treated S30V and S30V is only marginally better. sharpens up a bit easier BUT on that calypso jr. you'll find sharpening a breeze because of the full flat grind.
