Im the same way, fir years I was happy usinf my crappy smith and wesson and kershaw fir wirk ant thought $100 is cazry to spend on a knife. Then I git sick of always touching up my knives every few says and decided to look for a better steel. My first 2 "nice" knives were soyderc centofante 3(a great lil ed knife that cuts like a demon) andbenchmade 530. I immediately noticed the difference in edge ho, ding and the quality. So I git a griptilian and then my fiest military (one of the best knives ever made, thank you Sal Glesser) and I was off. Then I got a kick fir carbon fiber and titanium and I was breaking the $200 barrier, then $300 when I got my 3 microtechs. Then about 6 minths ago, im looking in my knife case, yes there were knives I loved but most were just blah so I made a list if knives I really wanted and made my heart beat faster and I sold if mist of my 30 production knives for 6 ir 7 midtech and customs. Now I have a Hivack kwaiback midtech (a knife I wanted fir almkst 2 years and im abs in love with it), ADV Butcher, Thorburn/Van Heerden A2, Van Heerden m16, Shirogorov hati, zt 777, spyderco southard, camillus jolt (best $65 you'll ever spend, the unidirectional cf is worth the money alone) and I have a David Clark fortitude and Brad Southard Tolj midtech coming in soon. I tell ya, I could not be happier I djd what I did, yes I miss my socom elite, select fire, guardian tactical (I might still get one later) and my military collection, especially the cf m390 sprint but I pick up my kwaiback or a2 and the action is amazing, incredible smoothness, great materials and I love the design and it puts a smile on my face. Its been a while since a spyderco or benchmade put a smile on me, yes they're great knives and I still love them, knce im dkne with my list, im getting a few militaries back fir sure but I really have no regrets. So like OP said, don't be afraid to sell if yoyr collection and get what you want, life is short, wirry , ess and try to get as much happiness as you can.
