I find spyderco to be one of those knife company's with a very distinctive style made up of what traits they prioritize in their knives and who they appeal to. The people that have different tastes and prioritys than spyderco are baffled by spyderco knives, while the people who do fit them love a lot of them.

While I find spyderco's so often prioritizing the cutting ability, portablily, materials, fit and finish and ergonomics sensible, Spydercos thumb ramps do not seem to fit my thumb well, leading me to have to grip it in a "hammer fist" grip. So the question is why do some people seem to like thumb ramps so much?

And do all these thumb ramp fans have what might be considered a "hitch hikers thumb" where the thumb joint can bend farther backwards then people who have straight thumbs? I have also noticed that Eric's knive often have a less pronounced thumb ramp than sal, are there differences between their hands ? (hitch hikers thumb is known as a recessive trait) Has anybody else found a similar correlation?
 
I do not have hitch hikers thumb but find the ramps a perfect fit. That's looking at bigger ones like the Military, PM2, Ayoob and Szabo.
 
My Manix fits like a glove and I don't believe that I have irregular thumbs.
 
I have no idea what you mean by hitchhiker's thumb..... These Spyderco's fit flawlessly!

I didn't say that spydercos only fit people who had "irregular" thumbs, I was only wondering if the people who use spydercos are more likely to have thumbs that bend backwards more. I can only barely bend my thumb backwards enough to resemble the ramp on the PM2, and I can't fit my thumb onto the ramp of my persistence while doing any cutting. 802-303 (why that name so hard to remember!:o) you thumbs appear to be bending to about a 90 degree angle where as mine only bend to around 170 degrees.
 
I'm technically left handed, and that thumb only bends to 110 degrees. But I never put much thought into it until I saw your post. I've always loved a choked-up choil style grip on my knifes, and Spyderco always seems to nail it. And looking at the angle of the ramp on my PM2, and the natural bend in my thumb. It's perfect.

Maybe the jot singh khalsa would fit my right thumb.....
