Well, all of them really.
The Tenacious was my gateway knife, just to try one of those funny-looking Spydercos. I've had a couple dozen, sold off a few while consolidating the collection, but still have eighteen or so. Benchmade started for me with a 710 bought used on The Big River Site, of all places, just to try out that AXIS lock thingy. I've still got two dozen BMKs and am really glad I took a flier on my first Grip, too, as there's now five of those, though no stock scales on any.
A lot of those I was glad I gave a chance were knives by makers that moved up me progressively in price level. My ZT0350 gave me an in to the better KAIs, though I never did have a Kershaw, and while the 350 is gone now it's led to four other ZTs.
It seemed dumb to me to pay 300 bucks and up for a knife, but I tried one just to see and my first CRK has begotten six more. That much for a heavy, overbuilt tank of a Hinderer? No way, right? My 3.5" XM18 begat another, then an XM24 and an MP1. I gave lionSTEEL a try with a great deal from a member here on a Damascus TiSpine and it's led to two others from that maker. I tried Wilson Combat with a Les George Eagle and now have bought 4 WCs and another Les George. Same for my first Shiro, which was fairly well researched and bought with the advice of a couple members here. I love that one and the other four Bears in my den.
There's some singles in my collection that I'm glad I tried an enjoy, though they haven't (so far) led to more--Olamic Wayfarer 247 and North Arm Skaha are two like that. There've been some clunkers along the way, though not so many, and a number that I liked OK but wasn't carrying or enthused about that I've moved out. Overall, I'm pretty glad that I've tried every knife I've picked up if only to find out it wasn't something I wanted to keep or to buy more like it. Such is the way of the knife knut.
