I have the 1620H3, my second Scallion (actually third since I bought two 1620H3s from Wal*Mart). I bought it to have on hand while my Twitch II goes back to SOG for a new spring.
The first Scallion I bought was also an H3, but the finish on the handle was so rough it wore out my watchpocket quickly. I promptly returned it. At the time, I felt that the H3s were refurbs, and to this day I still do not believe that these are TiN coated blades; they feel and act more like epoxy, similar to my Ontario Spec Plus.
I liked overall design, however, and did buy a red Scallion from Bass Pro. The anodized red finish was much smoother. I kept this knife for about a year, before selling it off for $20 in favor of the thinner AUS8 blade of the Twitch II.
This second H3 I bought as a temporary replacement isn't as rough as the first on I bought, and it actually smoothed out rather quickly. I really like this one again. I will probably keep it even after I get my Twitch II back, because I like the design much better. The torsion spring is more reliable, the safety can be tightened down as to not engage at all, and the liner-lock design is much more ergonomic than the lockback design of the SOG.
Now, if only the KERSHAW etching wasn't so outrageously HUGE on the side.
BTW, my date code is "MAR 07". Anybody know when the started using alphanumeric date codes rather than strictly numeric?
