Detent Ball Ramps.

I don’t spend a lot of time here so please excuse me if this has been covered ad nauseam or if I’m off base here…. but, why are demented ball ramps not standard on high end knives?

I’m fiddling with my new Spyderco Nirvana and the transition when the detent ball hits the blade could be so much smother.

I’ve wondered the same. That abrupt transition seems out of place on something the maker has spent so much effort on already.

There is a Break In with just about anything mechanical ~ Some times what we think will we feel right off the Bat with a new purchase and get dissapointed ~ Just takes a bit of adjustment.

I have also wondered about that. Why do most knives not have this little ramp? I have been tempted to take a Dremel and put one on some of my knives, but haven’t gotten around to trying it yet. This isn’t my photo, but it shows the ramp.

 

[naccibobacci]

Exactly. That should be standard on any high end knife.

smother.

Yes, kill the roughness.

Just a FYI.

If you modify a knife with a detent ramp be careful not to overdo it. It can affect lockup. Especially if it is an early lockup.

Hogue has a built in ramp on the blade that allows the ball to ride smoothly up to the detent. Quite a well thought out design.

I have created several detent ramps (one example below). I start them using a small, half-round diamond file, and finish by wrapping a small drill bit with 2500 sandpaper.

These are the files I use, they can be found on Amazon for $15, search for "Diamond File FIL-974.00", the seller is Eurotool.

Thanks! That makes sense.

My thoughts is that might make the blade a little too easy to close.
