Title: best way to sharpen shears
Post by: TheCaptain on May 28, 2012, 10:02:15 pm
I'm having a fecking nightmare; my spanking new shears have been awesome but are not as blunt as anything - flew through my first three ewes but they went dull on the fourth and it take an absolute age. I've got a sharpening stone but it doesn't seem to be doing the business.


Any top tips? Sharpening angles/direction/tools (dremel?)

It won't be a problem with the sharpening stone, it will be the way you are using it.

Difficult to explain how to do it - you really need to get someone to show you and even then you may or may not find you are good at it. Seems to be one of those things you either can do, or can't.

My OH taught me to sharpen things many years ago and now if he needs anything (other than shears) sharpened he gets me to do it for him.

You may need a finer sharpening stone.

This guy is using a wheel, but it's useful I think still
How to Sharpen Tools : Sharpening Sheep Shears (http://www.youtube.com/watch?v=hKBMNdtjppI#)

[quote]How Often To Sharpen?How often do I need to sharpen my blades during shearing? Is one pair of blades enough? And what kind of stone should I use?
I sharpen, or hone, my blades after each sheep I shear. It means a little setting up for this, and fifteen seconds taken between sheep.
It also means a final bevel on the blades that is ground thin enough to be responsive to this light honing.
The idea is to keep a very sharp edge. If you have the knowledge to do this I'd recommend it. Sharp shears make the work easier, the effort of the hand, and attending effort of the mind, less.
If you are using the smaller Number 10 blades and have not pulled them back to take more wool at a clip, and don't grind the bevel thin, then a good bench-top sharpening can be sufficient for shearing 10 to 20 sheep,depending on the shearing.
This is what I remember from once shearing this way. I'd carry two shears, plus an older pair as a backup, and sharpen at a bench each morning before going off. The kind of sheep, and the time of year though, make a difference—the density and strength of the wool, the grease and sweat present.
A diamond stone, soft Arkansas, or common "hardware-store stone" will do for sharpening.
Lubricate the stone with soapy water, or a honing oil. "Three-In-One" brand lubricant (used for sewing machines) does well.

A new stone needs to be soaked, in either the water or the oil, so the lubricant floats the abraded metal particles from the stone's surface 

Ok, failing to make either the quote or the pre-WYSIWYG way work, but here is a shepherd talking about keeping shears working.

I must sharpen my dagging shears.......

For my gardening equipment I use a sharpening stone and some 3-in-1 oil as described earlier but my best efforts never seem to stay sharp for long. I suspect that will probably the result of my limited knowledge and experience so hopefully it will improve over time...

Sometimes if you have sharpened a blade alot, you may be sharpening into the shoulder and it will need peening - i.e. the endge will need to be hammered thin again.

I have found Jakoti shears to be fantastic for hand shearing my Greyface Dartmoors, they are self sharpening to a degree but a little rub over the stone gets them tip top again. They are extremely sharp, and I have removed pieces of myself before now! Most shearing suppliers stock them and they are about 20 quid a pair.

I wouldn't recomment Jakoti shears for mountain or primative breeds - they have too many corners.

The shears or the sheep?  :D

Bu**ger!  Went out and bought some just before your post - it was the 'self sharpening' that tempted me!  Hope my Beulahs haven't got too many corners!  Will let you know!

GFDs have lots of wrinkles and are very easy to cut, whatever the breed you need to be careful!

Having clipped with the hand shears on anumber of occasions I can fully endorse the joys of electric and the handpiece!! Fair play to you,your harier than I! It looks good and sounds lovely with the hand shears but I'll stick to the machine all the same! :D

Hi TheCaptain,

The problem is probably the shears, what make are they?
All new shears are only fit for dagging really, most blade shearers set their own shears and grind them until razor sharp.
If you are shearing a lot of sheep then the shears could do with setting, I could give you instructions.
The best way to sharpen shears for doing a few is a quite coarse oil stone to keep a flat edge.

Hope this helps,
Philip :sheep:

burgon and ball - I've got two sets; one dagging and one shearing set. I've ground the dagging set and they are now sharp as hell and working really well. I didn't want to grind my actual shearing set as I thought the sharpening implement supplied would keep them sharpish. Not so much! Off to grind them now!!!


p.s. Have seen somewhere that some people give a slight grind on the opposite side of the blade too - recommended or just one side?
Title: Re: best way to sharpen shears
Post by: SingingShearer on May 31, 2012, 07:54:42 pm
That is the problem, Burgon and Ball shears are made of softer metal than some, the best make are the South African Rosa shears which are harder steel so hold their edge better.

No, it is not recommended to grind the bottom side of the blade, you can rub gently with an oil stone to take the burr off after grinding, you can also swag them (grinding from the flange on the opposite side of the blade to the tip) so as to reduce drag in the wool.

Hope this helps,
Philip :sheep:

I took my shears to the grinder - sharp as hell now so hopefully they'll be sharp enough to get through a few tomorrow.


thanks Phillip, I was scared to go as grind crazy as I did...


How would you slum a pen, just out of interest?
