This is a badge bit (BB) that is part of the PEP curriculum.  Completing this BB is part of getting the straw badge in tool care.

Pruning shears are frequently used in chop and drop. Unlike a machete, pruning shears allow one to precisely cut very small branches and stems of nitrogen fixing support species and "weeds" growing into food producing species. They are also much safer to use when working in groups. How you sharpen your pruners will depend on weather you have an anvil or by-pass style.

Here's a short video showing how it's done. Don't grind the flat down. The flat only ever comes in contact with the stone to polish the surface or remove the bur.


These are hedge shears, and not pruning shears. The technique is the same for by-pass pruning sheers and loppers.



Requirements to complete:
- Disassemble pruners and sharpen the edge properly (depending on whether anvil or by-pass), including both primary and secondary edge if applicable.
- Remove excess sap and other residue. Some "staining" is to be expected.
- Oil sufficiently for smooth action. Oil can't be petroleum derived .
- Please make sure your that your tool are pruners (not loppers or scissors)

To get certified for this BB, post the following:

 - Pic of dull edge or poorly cut green stick.
 - Action pic with disassembled pruners showing method of sharpening.
 - Pic of reassembled, sharpened pruners possibly cutting green stick
 - Describe the sharpening method and oil used.

Here is my submission for the Tool Care - Straw - Sharpen Pruning Shears BB.

So, I was cutting up branches to make micro-hugel material for the bottom of container gardens and the pruning shears were shredding instead of cutting the small branch material.  So, I grabbed some soapy water, a whetstone, a screwdriver, a wrench, and some steel wool and got to work on the pruners.  The video gave me the knowledge and confidence to disassemble and properly sharpen my shears!  Some steel wool removed all the sap and "staining" on the frames.  I sharpened the cutting edge then removed the bur from the backside using the whetstone.  I also ran the "bypass" blade over the whetstone (flat - not sharpening it) after cleaning it with soap and steel wool.  A good scrub and some sunshine (to dry all the parts) and the reassembly went smoothly.  I put a couple of drops of olive oil in the mechanism (before tightening the bolt and lock screw).  I did not use any petroleum-derived oil during this project.

To document the completion of the BB, I have provided the following:
 - Pic of dull edge or poorly cut green stick
 - Action pic with disassembled pruners showing method of sharpening
 - Pic of reassembled, sharpened pruners possibly cutting green stick
 - Describe the sharpening method and oil used (above)

I took apart my pruners, soaked them in alcohol for an hour to clean them, sharpened the blade, put it back together and oiled it with coconut oil. I've included a video of them cutting a green stem after being sharpened.

Edge case submission
Today I thought I would sharpen my hedge shears ready to complete the chop and drop BB. I sharpened the primary edge with the file then used a diamond honing stick to sharpen the secondary edge. I tested it on a piece of paper which cut beautifully. I then wiped them down with peanut oil ha ha.

Staff note (Mike Haasl) :

Hi Alex, looks like you fell into a gap between what we call "Pruners" in the US and scissors.  I fiddled with the scissor BB: https://permies.com/wiki/127867/pep-tool-care/PEP-BB-tool-straw-scissors#1008271 so I think it's a better fit for this submission than here in this BB.  Would you mind reapplying over there with the same info and I'll make this post of yours go away?  Thanks!

No, they are definitely hedge shears. Which are a type of pruning shears. Scissors are held with one hand and are usually upto 1foot long. These are held with two hands and are 2 feet long. But oh well. I'll just sharpen my secateurs next time.

I think that hedge shears fit very nicely in the "Loppers" category. My 2c.

I decided to sharpen my back up snippers because they suck. I was hoping that shapening them would make them decent, but I think what I don't like is the design. Now they are sharp and sucky. Maybe one day I'll sharpen that second edge and it'll help.
