QFT!it's a slippery slope man... You'll go from 20 to 50 then 80. From 80 you'll jump to 100+ then 200+ then customs and midtechs...
Welcome to the forum!
I remember shopping for my first modern folder. I looked at the mid-grade Spyderco line (i.e. Manix, Sage, etc) and thought, "Wow! Who pays $80+ for a knife?" I settled for a Tenacious and thought I was "splurging" at around $30.
Fast forward a couple of years. My last several purchases have been in the three-digits. Just today I pulled the trigger on a William Henry E10. And I'm eying a Sebenza 21, Strider SNG, and William Henry Atlas.
So many knives, so little time.
