I have the 21 only and love how it has the extension included so you're ready to go. Unfortunately the plastic sleeve on the OD has chipped on mine with little use at home. And I'm in no rush and little use. Dunno if it's a fluke but it wouldn't last a week if not a day used commercially based on my usage. It'd be nice if they sold the sleeves separately but I doubt they do. I understand its plastic and it's not like Koken plastic will outlast HF but they should sell the sleeves separately to justify the price














I'd be curious to hear your opinion on them.
