Well i wanted to get a convex edge on my GW and it was to late to go to a hardware store for any sharpening supplys so i said to my self " is there any other way" i looked at my double kneed carharts that are pretty rough so i tryed to drag the knife across it for 45 min. it actuly was thickening the edge without dolling it. so i did it for a total of 2 hours (pretty long :)) and its not any sharper then the oringanl maybe a little less (not by much) but its thicker, but i havent done anything to it besides the pant leg.

i dont know how to finish the edge to make it super sharp. how do you make it super sharp?:confused:
 
one thing ive learned re: convex grinds:

if you are using a soft backing, and push too hard, the abrasive wraps around the edge and ends up dulling it.
 
I'm not entirely sure what you mean by "thicker edge." Do you mean that the edge bevel is taller than it was before? If so, don't expect the edge to get sharper if you are working the shoulder (where the primary bevel meets the edge bevel).

Pressing too hard can dull the edge. Let the weight of the knife do the work.

Color the edge with a "sharpie" so that you can see when you are working the actual edge of the blade.

I use wet/dry sandpaper backed by leather. Start coarse and work to finer grits. Finish with a loaded strop.

Ask this question in the maintenance forum and you will get a much better response as to how to get that "scary sharp" edge.
 
I often use my carharts to strop after sharpening.Works fine to get the burr off. Havent tried it with a Busse though.
 
"Justabuyer" will be able to help you... and there is a lot of info contained within his threads.

I use 180 grit then 600 grit wet'n'dry on top of a strip of foam to form the shape of the convex edge.

Then I use a buffer with 8" wheels on a 6" bench grinder to take the edge to a flawless finish.

when i sayd thicker i mean... i cant really explane it very well a v gos like this /\ i made the linesmore "u" like or bent thats the best i can explane that.

should i be pushing the edge into the strop or draging the edge or pushing the edge into it?

does a steel have roll in convex edges?

For convex sharpening/stropping the spine should always be ahead of the edge..... i.e... the opposite of cutting into it.

For a flat grind to convex edge...as found on your GW... the idea is to form a curve instead of a straight sided V.

A mistake I still make from time to time when I am not paying attention to what I am doing. Good advice.
 
ya i am going for a flate primary grind convert my v into a flate convex.

i wouldn't advise this on carharts with only one knee i did that and almost really screwed my leg up ( when i first started i had a single knee and was pushing [when i almost messed up my knee i knew i wanst suposed to push] and it cut the pants and gave me a "paper cut")
 
HEHEHE..... i guess you havnt read my other threads i am only 14...( almost 15 b-day feb. 18)might get a ash-1 .they wouldn't be smart anyways (sharpening knives while drinking...)
you might asume that from the spelling also i just type fast and don't care:D

Well that puts things in perspective.

Forget the "Carhartt pants sharpening"

Get some 600 grit paper and practise on a cheap knife.

Jee whiz mate what are you doing with a 200 dollar knife???

I wish my parents were that cool when I was a junior, although your 187USD knife costs me 262AUD after BCS shipping :(
 
how can i possibly screw it up to badly with my pants if theres something wrong its not going to get worse very fast. but i guess you guy kmow from experiance.:o

i dont have a knife this thick to practice with will that effect it when i start doing it on the real thing?

i chose to make this and $50 my only X-mas present from my parents thats how i got a 200 dollar knife.(and plus i get really good grades :D)

i just read the bark river sharpening page and i tryed the hard plastic tupe test and it didn't bite in only by the choil and at the tip does that mean if i jsut finish the tip and choil and then run it with ummmm. lets say 2500 grit to make it super sharp its a realy convex edge, or dose that dont not always work?
 
Congrats on your choice of Christmas present. Sharpening is a thing that takes a little patience, you will not get instant gratification. If you are going to follow the steps on that Barkie page, you need to follow all the steps. There are no shortcuts. The blade has to be sharp with the coarse paper BEFORE you can move up to a finer grit. It will never be sharp at 800 or 1500 grit if you don't get the edge right with 120 or 200.

For another perspective on, go over to the Maintenance forum and search for thread started by nozh2002. He has done some great work on Game Wardens with diamond stones. He also has put up some good videos on youtube.

There was also a great thread here a month or two ago by justabuyer, an outstanding tutorial on reprofiling and convexing.

Good Luck!

You won't screw it up... INFI is by far the toughest steel I have worked on.

Stropping on the leg of your pants or on a piece of cardboard will work once the knife is sharp and you just want to bring the edge back after it has been dulled with use.

Understanding the angles and techniques involved in convex sharpening is the good stuff... and it is well worth using a cheap kitchen knife to practise on.

The fact that your practise knife is not as thick as the GW is not that important... what you learn from getting the edge on the kitchen knife sharp will be very valuable when sharpening your GW. :)

Resinguy makes good points..... and following the instructions on the Bark River page, using your practise knife, will help you to understand the process.
