Does anyone know how to sharpen a serrated blade

[jackcbr]

Hi guys

i need a bit of help. I've got a rescue knife for when I'm canoeing, but when it turned up it was next to useless for cutting. I've sharpened up the normal edge, but not sure how to do the serrated edge. Now I've not got any fancy sharpening kits, just whets stones, wet and dry and a falkner DC 3 and 4.

any tips?

cheers

Jack

Have you tried a saw file Jack.

Is that the Lomo knife? I've been toying with getting one recently

I think you need some triangular or narrow-round files or stones for serrations

get yourself a set of diamond needle files. they'll do the trick

or might you be looking for a budget solution, get some wet and dry, grits 400, 800, 1200, and if you want to do a good job a 2000 as well.
and shape a stick into shape to match the serrations, stick on the wet and dry with a spray glue, or contact adhesive ( spray glue is easier and better though, as it wont have lumps and bumps in it and has less deformation under pressure)
and voila you very own, limited use sharpening stick/ file.
Finish the entire process of with a nice strop and some stropping compound ( like perhaps Smurf poo), and you will be good to go

Hope that was useful to anyone
Yours sincerely Ruud

there are special sharpening stones for serrated blades.
they are usually triangular or round.

Hi Jack

Well the knife itself may or may not rock your boat, but the advice about sharpening serrated edges in this review (see post 22) is good!

See you in Sussex sometime soon.

Regards,

Dave

Cheers Guys

to answer a few points:

yes it is the Lomo and it is nowhere near as sharp as their demo video would suggest, but that can always be sharpened. It's not a bad bit of kit and hopefully if stopped by the police it's lack of a point and bright colour would help convince them I'm not a knife wielding maniac. Mide you the axe and bushcraft knife in my bag might say otherwise.

Will check out my needle files, if I can find them.

nice looking sharpening tools, sadly I'm fly to Scotland on Thursday so don't have time, or budget to buy new kit.

the wet and dry sticks (sorry for over simplifying) is definitely doable.

but the winner is the "just sharpen the flat side". As this will get me ready for Thursday

thanks for your help guys

I think that the only possible way to learn how to do that is to follow a video tutorial. I mean you can explain of course but it's better to watch how it should be made. This video here http://mp3pole.com/video/9dUb4z7JC8...rpening-How-To-Sharpen-A-Serrated-Knife-Blade is a like more than 10 minutes of explaining what you need to do and how, it helped me a lot to understand the technique and the main principles.

 

[jackcbr]

Yep, that's a good tutorial. Shame I don't have a ceramic rod.

Thanks for sharing

Aldi had some diamond files last week.

One tip I've been given (although I've never used it) is to use a wire wheel on the ground side of the serrations and a stone on the flat side.

 

[drliamski]

Buffing wheel and compound works.

Last time I sharpened a serrated blade I used fine wet and dry around cocktail sticks and bamboo skewers. Wrap a section around the stick, hold the loose ends closer to the stick so it's nice and tight. Worked a treat.

Crudest yet effective method I saw. Elderly gentleman fixing the blade on my sawtable. He just took an electric grinder for angles and sharpened with patience every tooth of the sawblade.
should be easy to do on a small knife. Sharp as anything now that sawtable blade.

I would use diamond needle files, can be picked up quite cheaply
