Anyone made a boyd detent on a chaparral?

I recently picked up a chaparral and I found myself missing the boye dent. The chaparral is a great knife but the back spring is soooo stiff. I have begun working it in by opening and closing it hundreds of times, but it is still pretty stiff. I am wondering if a boye dent may help with the pressure on the thumb. Has anyone tried to make one on a chaparral or other model with a stiff back spring? And if so has it helped at all?

A boye detent is a cutout in the lock release of a lockback to precent the lock from accidentally being disengaged. Basically a "safety" feature of the lock. I see what you're getting at though, making a relief on it to soften the pressure point on the lockback. What about flattening/rounding off the lock? Taking the hump out of it will give your thumb more surface area, and rounding off the corners will cut down on the sharpness.
 
Boyd detent?

Its called a Boye dent. Did you open and close the pivot in warm water? You'd be hard pressed to find Spyderco backlocks with a smooth opening. They are very few
 
I have the same knife, and after use the spring eases up to a nice medium tension. Making the dent wouldn't be too hard I guess, if I was going to try it I would use my dremmel

Thats how I was thinking of doing it...a dremmel seems like it would be easiest.
and thank you redfeenix, I didn't realize I had the wrong term. Fixed it now
 
Lack of a Boye dent is my favorite feature on the Chaparrel and Native 5. I feel it is harder to unlock back locks that have the dent because it makes you depress the lock bar deeper into the handle cutout.

Redfeefix- have you handled a Native 5? It is the smoothest back lock I've handled to date.
 
I have the forum, fluted Ti, and moonglow N5, unfortunately they all were gritty :(....

Many people have said the G10 N5 was pretty smooth, its the only one I don't have. That being said my Calypso Jr. ZDP is ridiculously smooth I can literally open and close it like an axis lock Benchmade. Till this day it remains my grail Spydie! And I do agree I prefer lockbacks without the Boye dent.
 
I have a 110v forum, and regular production Native 5. Neither has any grit at all. Super smooooth! Luck of the draw on production knives I suppose.
 
I prefer the Boye dent, but it just wouldn't look right on the Chaparral. I think the thinness of the lock bar is the reason some people are experiencing discomfort while unlocking it, not the lack of a dent. I have big thumbs, though, so I naturally have plenty of surface area to work with.

You said it. My Chaparral CF is smooth though like a hydraulic opening
 
There is a difference between smooth and resistance. I have never had a Spyderco lockback that was not smooth, but very few are low resistance. My Centofante 3 has the least resistance of any lockback I have, and I have heard that from other Cento 3 owners. If you feel grit or non-smoothness you should wash it under warm soapy water. Most likely it has some metal shavings or other debris in the pivot.
 
The pivot is smooth as glass! The problem I was having is that the spring bar seems to be a bit too tight because it is difficult to disengage the lock. After the lock is disengaged the blade easily moves into the closed position. After two days of opening and closing the knife and leaving it most of the way open but not locked (so the lock bar is in the same position as if I were pressing it) it has become easier to disengage. Still not the easiest but it is getting there :)
