well told CM.
my story is like it, starting with their first PST.
today i carry the Wave+.
like you, i've considered upgrading to a better blade steel but figured i wouldn't abuse it as much as i would with a standard steel blade, and thus get less use out of it.
besides, i'm never without a high-quality razor-sharp lock-blade folder in my front pocket.
thnx for sharing, and enjoy your Arc.
