H1 in SE holds a very good edge, especially a SE hawkbill like the Tasman or Spyderhawk Salt. I also really like the SE hawkbills because the "teeth" on them aren't over long/thin/pointy, like on some other models, which can often snag. I use my SE Tasman cutting lots of hard plastic straps, have had it for years, and it's yet to need a sharpening.
