Notch

[Gary W. Graley]

Most that know me, know of my lack of foundness for the notch that
some makers put just before the edge, some call it a choil others, something else.
I call it annoying and today it struck again.

I'm down in the hot muggy country of Trinidad, steamy is more like it, but
then it is the rainy season!

Here on business and while I was cutting off the heavy plastic that we
wrap our machines with, the Junk Yard Dog II kept catching the material
in that notch and hanging up, man that was and is frustrating, I think when
I get home I may do some mod to it to make that first area a sharpened
serration or something, hanging up on material is not just annoying, it is
also dangerous when you 'think' the knife will continue on it's path but
is hung up in movement, argghhh...crazy stuff.

I know some LIKE the notch so it provides a clean way to sharpen their blade
myself, I've not had a problem without a notch.

Some knives have a more angled slope to the notch so material doesn't catch
but rides up and onto the edge, that is a good compromise, which I may also
attempt instead of a serration.

Here's a shot of the offending notch area;

while the folks here in the plant were quite impressed, the did notice
me opening the knife and cutting stuff a few guys wanted to look
at it a bit closer. They seemed quite impressed with the knife overall.

Ah, the evil "sharpening choil". I'm not a fan of them either. I usually just round it off, and sharpen the round part. But making it into a serration is a great idea!

I instead widen it and make possible to put index finger in it when cutting. Without this it does not make sense for me too.

Thanks, Vassili.

Vassili, good idea, for me, I wanted the larger blade and like the extra length
of the cutting edge, I'll see what I can do once I reach home for a few days
after this trip I head to the middle of the USA for a week and then maybe to
Oman and then to Kiev, busy traveling these days!

Edited to add, this of course, isn't tied only to this knife, but to all that have
the 'notch' it's just that I thought it being so close to the guard area, I'd not
run into this problem, but it was. Other knives are more pronounced than this.
But other brands do not have a notch and run the edge right up to the end.

I did not shorten edge, just cut out flipper:

this is what was originally:

I think it play better with concave curves of the handle to have concave flipper as well.

Of course you may sharpen edge right to the flipper - it is not too far .

Thanks, Vassili,

Nice work, I've used the profile ceramics a little tonight to soften the
angle of the notch, hopefully that will make it not grab as bad as before
regular cutting, probably not a problem, but in cutting things like cloth
plastics, things that bunch up, they tend to catch more readily,
the plastic banding around the boxes, whoa, sliced like a crazy
junk yard dog!
