This is some what of a response to the thread "Spyder Hole- Opening Method"

Anyhow I typically like to flick my spydies open with my thumb, but I have noticed that on spydies with Full Flat grinds, the hole is very sharp. This causes chaffing of my thumb nail and overall feels very uncomfortable. So for my spydies with FFG I just open with thumb purchase or spydie drop.

Anyone else experience sharp spyder holes?

Sure this has been covered already
 
I find that the 'sharp' edge on the spyder hole, helps alot when opening with the pad of your thumb. It grips my thumb better than say, if it were chamfered or had a rounded edge.
 
I love the sharpness for thumb pad opening but as far as flicking with the thumb, it's out of the question in my opinion. I have no trouble opening my Saber Ground spydies with the less sharp holes as well as flicking.
 
In another thread the ever wise powernoodle said this:

"I have stated this elsewhere, but I very, very gently chamfered/rounded over the edge of the Spydie hole on my Sage 2 with a rat tail file. It did not seem that sharp to me until I sat there opening it 900 times as I sometimes do. If you like it sharp, thats groovy, but you can barely round it over so that its not visible to the eyeball, but still easier on the thumb. I also smoothed out that line that bisects the spydie hole. Not enough that you can see it, but it just makes it less sharp."
 
Was thinking of doing this, but at the same time im okay with opening my Sages' with the pad of my thumb :p

Thank you for bringing that up CGM :]
 
I normally open by flicking with my index finger, or I open with my thumb (without flicking).
 
I've smoothed mine out with 2000 grit paper a few times. I stick with low-speed thumb opening anyway, but it gives it a more finished feel.
 
Fully chamfered opening holes suck [see discussions about the opening hole used on the Benchmade Skirmish]. The opening holes on all my old-school AFCK's are smooth and a real pain-in-the-ass to open because your thumb literally slides off the hole.

Give me a sharp 14mm Spyderhole any day - I can always take some 600 grit sandpaper to the edge if it's too sharp.
 
Thats why I was confused, I didn't realize that these were two separate threads.

Anyways, I don't find sharp spydie holes to really be a problem-my thumb quickly got used to it, but I don't like it when they inside of them isn't smooth. Occasionally you'll see spydieholes with some spatter on the inside of them, which isn't sharp enough to cut you or anything but does rub against your skin/nails kind of funny. Not a huge deal but I can be a perfectionist.

Man speak truth. Far better for it to be too sharp than to be chamfered. The Skirmish could have been a great knife if they hadn't decided to do a full chamfer of the hole.

You can always mill it (or drill) and increase the size of the hole until it reaches where the chamfer starts. I have different plans for mine but if I weren't going to make my mod that is what I would do.
 
Sal feels the crisp edge provides better grip for you thumb and thus more reliable opening. Lots of users agree. I do too, to a point. I think it's important on models with smaller Spyderholes, like the Kiwi, so I leave them as they are. I don't find it a factor on models with 14mm Spyderholes, so will sand the edge just enough to soften it slightly. Not chamfered, just not crisp. That's easy enough to do, and certainly easier than making the edge crisper to gain traction would be if Spyderco chamfered them.

You can always smooth out the edge of the hole with some sandpaper? I personally like it, provides alot of "bite" so I can flick it out fast.
 
I've rounded over the Spydie hole on a Native III too much and had my thumb sliding off the hole. It resulted in a very frustrating experience. I had to regrind the inside of the hole to bring back the sharper edge. There's no issues if you knock the edge down just a tiny bit but don't round it.
