Can I sharpen scissors on the PE? If so, any advice or tips?

Good morning maggierving...You can sharpen scissors on the ProEdge using a fine grit belt such as a 240 grit Aluminium Oxide belt or the 600 Trizact. Scissors work using a shearing action rather than a traditional cutting action like a knife. This means that the shearing faces only need to have a crisp edge to work efficiently. Because different scissor manufacturers use different shear angles for the cutting faces it is best to place the face gently against the abrasive belt ensuring there is no visible light between the scissor face and the belt and gently draw the scissor blade across the belt. This should only need to be once or twice to get a perfect clean crisp edge. Repeat for the other blade and your scissors will now cut beautifully.

Hi Clive and Co,
Can you please add a video of sharpening scissors on the proedge to your youtube videos? It's ok if it's not a good quality video I just want to see it being done by a professional before I dive in. If you just put proedge and scissors in the title we will be able to find it.
I think the videos are really helpful and unfortunately I'm living 13,000kms from where I brought my proedge so getting advice in person isn't easy.
Thanks
Kat

Also I wish to see a video of someone who can sharpen a scissor, i have a Tormek T4 but i will invest in a good quality belt sharpener and look at Sorby just now, nicer scissors is not prefered on Tormek but i think the Trizact belt will work verry well.

David, thank you for visiting our forum. You're right the Trizact 600 will do a great job sharpening scissors- please refer to the earlier advice from Clive further up this thread. Currently we don't have a film showing the Proedge sharpening scissors but it is on the agenda for the new year. If you've not already, sign up for news on our website and be first to hear the latest at www.robert-sorby.co.uk/resources/contact-us.html

Well I have never sharpened scissors before, but I have a couple of pairs in the workshop which have been abused cutting abrasives off rolls, or cutting rope when I am making rope bound things! and possibly opened a paint can or two!!!
I kind of dared myself to make a video for this thread, literally never made one before, not even a clip on my phone, and was further hampered by the fact I lent my camera to my daughter ages ago...
Anyway, recovered the camera, downloaded some video edit software and made a video. Editing is shoddy, script writing is non-existent, but scissors go from not cutting paper to cutting paper so the result is good! Actual time at the belt is 2x speed, this has the benefit of both shortening the video and dropping the soundtrack of the motor running!

I use a lot of different pairs of scissors and shears to cut different things. I have sharpened a few of them by hand in the past. There is a slight angle of 10-15° coming off the face. I like to take them apart and do each half separately. This way, I can get all the way to the inside without damaging the other half in the process. The number of strokes done to one side has to be done to the other side as well. This makes for a balanced sharpening.

Hi Antoine
That makes sense, I don't really know much about scissors, the two pairs I have in the workshop are completely different in profile and I am sure that there are many different designs out there. Taking them apart is not an easy option on my pairs as they are both riveted, but I would guess that more expensive scissors are fitted with a screw so tension can be adjusted.
I used the 240 grit belt in the video which seemed pretty good, what grit would you aim for on more expensive hairdressers type scissors?

Scissors are like miniature hedge shears. 240 grit will do just fine. But if you want to cut fine paper, I would use a finer grit so that it won't rip or snag the paper. I had a pair once that were riveted, so I bent one side in a bit so that they would touch. If you want to hone them down, use a coke bottle or something that is glass and try pulling and cutting it several times. This would help remove the burrs. You can also use 600 grit wet/dry paper and hone the face a little. Antoine

I'm sorry for answering the last part of your question. I use to cut hair in my earlier years. One thing you must never do with hairdresser shears is to never use them for anything other than cutting hair. Some scissors, you can feel the gritty feeling when closing them up. Not so with hairdresser shears. They are so finely ground that it feels very smooth. I have not sharpened them. I simply bought another pair. But if you wish sharpen them, use a 1200 grit or finer. there is an emery cloth you can use. Place it on a hard surface and add just a small drop of 3 in 1 oil and work it back and forth from tip to the inside as if jabbing keeping its angle. Speaking of angle. On regular shears the angle is around 110° taken from the inside of the face. I got this angle by looking directly into it from the point.

Robert Sorby has a Trizact sanding belt WPE3000T. If you use this and being cautious of the angle, you could do a fantastic job of sharpening scissors. If you take a small piece of wood and cut it to the desired angle and use it as a guide to draw the scissors across, the angle will be consistent for both sides. I would set my rest at 90°. The base is at 0°, the height is at 90° and the hypotenuses is at 80° to the inside of the angle or 110° to the outside. Have I confused you enough?

Thank you Antoine, that covers it very well I have never bothered with scissors before, and knew hairdressers paid a lot for and prize'd their scissors though to be honest I have never paid them much attention! it is only to answer the question at the top of this thread I thought to give it a go, and was pleasantly surprised at how easy it was to make a big difference, I may even take some of the house scissors out and sharpen them now Will certainly have a look at the angles of them to see if I have any that match your description and also if they come apart for individual side sharpening.
