just wait when Yvsa gets back from his holiday,an sees what i did to his beloved Y C S khuk.

he told me not to be afraid to use it,cos a lot of owners think they are to pretty to use.

well i used it all right for 2mins OH MY GOODNESS :(

i havent got the heart to tell all now i'll wait for Yvsa to get back then post full story with pics.:p :)
 
You are not going to leave us in a cliffhanger for a month are you?

Can you give us a hint?

Only Sanu makes this model correctly. The other kamis have problems with it for some reason. They can make about anything else but not this one. Sanu has more duties now that Bura in not up and running so I think I'll just discontinue this model for awhile to stay out of trouble.

Ken I'm still around, just not open to e-mail from where I am.

What happened? Did the edge chip out or worse?

And the YCS is stilljust a khuk. If the kamis would make it like the wood model there wouldn't be any trouble with them as it is a convex edged knife just as all khuks are supposed to be.:grumpy:

On another note we finally made it into Phoenix around 7:00 p.m. last night.
Our daughters had torent a car dolly and come and get us from Gallup N.M. because the little Dodge lost its transmission.:(
It's now in the shop finding out what's all wrong with it, still had 1st and reverse. I figure it blew an "O" ring but what sorta ticks me off is that the transmission was worked on less than a year ago.
The good thing is that it won't cost us anymore than $100.00 for the dedutible as I took out a 100,000 mile warranty on the whole drive train when I bought the car.:D
 
I dropped a water pump pulley (in a jap. car) on a Saturday afternoon driving along the freeway outside of Albequerque, NM in 1996. Ended up staying in the dealership parking lot for an entire week.

I have heard more car-problem stories from New Mexico than anywhere else, except Kansas - where I fried my transmission 2 days before Christmas! :eek: (while making a cross country trip to see Grandma...)

I don't have enough energy to go into that story, but lemme tell ya = Kansas and NM are bad news for trips.

My wife's family got rear-ended by a semi in Kansas (amazingly, no-one got hurt too bad) and they have had major car problems in NM on several occasions.

What's the deal?

I've driven nearly the entire US and have only had problems in those 2 states.:confused: :mad: :(
 
hi mate,you lucky bugger allready on your hols,we dont leave till another 9 days,then its tasmania here we come.:D
ok now the y c s, i got it and it was lovely,took about 3hours oiling titivating it up,admireing it ect. them out the back to use it ,like you said its pretty but make sure i use it.
well i used it for about 2mins, first chop nice deep bite second again beutiful, so i let fly with about 4-5 more hearty chops, and wham something clanged into the metal fence in front.stopped and glanced at the blade. it nearly broke my heart, massive blade failure,
three large pieces shrapnelled of the blade,
largest about 3/4inch x 1/2 inch sorta half dollar shape, almost as if you had bitten large chunks out of the blade.
i just stood there, amazed and horrified, walked along the fence an found one large piece,i sure am glad no one was standing in front,it was big ugly an sharp.
i went inside had a coffee,and looked at the blade,the beutifull big belly was ruined.[the khuks not mine].
i took it reverently to the scanner an took a picture of the deceased.
then sent it to bill with a quick note of what had transpired.
bill promptly offered to replace with another khuk.
so i will wait for sanu to make another as i realy want one of these wonderfull big bellied y c s. you get a glitch and once again proves the point buy from hi with complete confidence in not only the product,but the backup service as well. :)

oh nearly forgot, what do you mean convex edge yvsa. ? are some khuks made with different edges.??
i remember reading somwhere the other day, about khukri blades are now edged differently to what the ghurkas intended them to be,and as such are not as robust as they should be.????
could this be right :confused: .
what sort of edge does an everyday use khuk in nepali hands have. if anyone here can emlighten me it would be most appreciated. :)
 
most HI khukuris come with a flat ground edge.

You can put a convex secondary edge on it, but it's not for the squeemish.
 
Kendo,

If you want to email that scan of the YCS over to me I'll post it on here.

I will humbly offer a reply until Ysva gets back online...
The convex edge is known for its greater strength and durability and was the norm from HI until recently (as I have heard from Ysva) Perhaps picture a cross section of a bullet to get a idea of what it would look like. (I recall a recent thread that referred to two bisecting circles...)
The convex edge describes one of three common edge configurations, the other two being flat and concave or hollow ground.
I fancy the bigger AK's and do some serious chopping with them. Had edge failures on two of them, apparently because of the shape...flat to concave instead of convex.
Art S. reground my 25" AK which is now terrific (Thanks again Art).
Just my pennies worth (not even $0.02)...
Hope this helps as we all await Ysva's expert comments.:cool:

Note that the general conclusions are pretty much the same as Yvsa's although they are not quite as vividly and entertainingly presented.:)

PIC ON ITS WAY not2sharp thanks.

yep that answered that convex blade question allright,and very well even dumbass me understands what to do now.
but i am going to get the local knife maker to put the edge on first, then i will maintain it.that way i am assured the temper, and blade shape will be what it should be,when put on by an expert.
then with all the good info here i feel very confident i can manage from there. :) :D :D dont know which one to do first probably the ang khola. :confused: by the sound of it, it will be money well spent.

OOPS HANG ON A MINUTE JUST THOUGHT ???
Bill will putting a convex edge on our hi khukris make our guarantee on the hi khuks null an void - cancelled. ???? :eek:
 
Here is an early photo of HI's new saw tooth YCS. You no longer need to chop with, instead you just run the edge over the surface and its' pattented serrations rip right through the hardest materials. It is guaranteed to scare women, children, and BGs.

Kendo,

Now that you have manage to create the prototype, it might be worth testing a bit further to figure out what RC this blade actually achieved. Perhaps the combination of a relatively thin leading edge, plus the new edge grinding process, contributed to the problem.

Thanks for sharing.

Yep, as Pragitam said, NOW they do:( I guess its the price of progress to power tools. I treasure my older khuks from HI that have the old convex profile.

Kendo,

That is one NASTY chip!:eek: Glad to hear you'll be getting a Sanu replacement--I don't think you'll have any trouble with it.

Yeah, test all your blades at home before you rely on them to save your life in the field.
 
ok i will take the deceased khuk with me when i get my large ak convex
ground, and ask the guy to test edge hardness,ect.
there is a custom knifemaker in a little town up in the hills near adelaide, called hahndorf. he makes custom blades, and offers custom sharpening.
i want to pull the handle off, and will keep it as a spare, for other khuks if needed.

yeah good joke about the ycs saw blade. i assure you i couldant have done a more thourough job of it if i had tried.
i am definitely gonna wait till sanu makes another ycs, doesant matter how long it takes theres no hurry.i got the other ones to use.
i will let you know the outcome of the blade test, and how the convex edge goes on the ak. :)

Ken that's what I figured when I 1st saw this post.:(
That happened to the very first YCS although it had only one chip it was about the same size.:grumpy:
I put the blade on my Grizz grinder and ground away the chip being very, very careful not to get the blade too hot.
Doing so got rid of the extra hard and thin edge. Now that YCS has a nice convex edge that will never chip out again.
I had the same thing happen with a GRS because the edge was too thin, hard and Not convexed.
I fixed it the same way and haven't had anymore problems with it and like the YCS it won't fail again.

IMO it isn't just the YCS that fails more often as shown by the failure of the GRS.
Any knife with a too hard and too thin edge is apt to failure. I had done a lot of work with my GRS before it failed.
 
Yow!

Looks like the guy with the metal dentures from the James Bond movie had the munchies...Not chipped too far in though, I bet with some work the bladesmith you know of could get her usable.
 
yep i thought of that ,take it to hahndorf, custom knives,its goin to involve a lot of grinding,the length of the missing bits is 2 and 3/4 inch long, and 1/2 inch deep at its worst.so to grind that out and try and keep a reasonable shape, would involve a hell of a lot of the forward area of the blade having to be removed.cost ?? dont know it would be on the time taken,probably cheaper to buy a new one.so back to ME DOIN THE JOB ??. i got a black texta and drew a line where the grind would have to go to, and it could be done sort of, but boy it would look ugly,AND IT WOULDANT BE THE Y C S no more :( .
then next would be the question of tempering, after about 1/2 inch of removal from the belly and the forward part of the blade,
what would the blade then be like ????.
from my understanding of the kami process they use a kettle of water on the edge to harden and temper ??. .:confused:
the main thing though is the safety of it all, i dont fancy doing the grinding job, as it will be a long process,and one slip and you could end up disembowelled :eek: :eek: .
so instead i have decided to take of the handle and strip down the scabbard, before i am temted to try.
this i think will be advantageous as i can see what is involved, and of course use the handle as a spare.
i will still be having the blade checked as to hardness, just out of curiosity. :confused:

and i will happily wait till a sanu made ycs becomes available in the future. :D :D
