Sparpmaker and Spyderedge? A no go on the longterm?

[Moltion]

Hey Guys
Im confused with sharpening serrations/spyderedge. Some say do loop by loop and some say just go down with it like with a PE on the Sharpmaker.
What im concerned of now is some say the sharpmaker will SE blades transform slowly to a PE. How is the long term use of the sharpmaker with SE blades in real? Do some of you have long term experiance with that?

Hi Moltion,

Welcome to our forum.

I recommend that you read David's forum post on serrations.

The serrations do eventually get rounded off, but this actually gives the knife better cutting performance in many cases.

I've yet to get one to PE on accident. Here's a Tasman Salt that's been used hard for over a decade, for example:

Yeah. Watch the vids, find the right angle, sharpen like a normal blade, don't worry.

Hi Moltion,

You should look into these two threads (as Sal has recommended already):

Multiple sharpenings with the sharpmaker will slowly round off the "spikes" a bit, but as Vivi has said this makes SE even better.
You'll never turn an SE edge "into PE" with a sharpmaker though. Keep in mind, you always sharpen (away) the scallops between the spikes too.

People telling you this are probably also the ones who say you have to use a chainsaw file, they only work in a sawing motion, they're for people who can't sharpen their knives, they're hard to sharpen...it goes on and on. Just watch the Sharpmaker DVD video and do what Sal says. It's that simple. You may need to use a sharpie marker to color the bevel and make sure you're hitting the edge apex, and then you may need to reprofile at some point and that gets to be a lot more work, but just sharpening the knife is done almost exactly the same way as PE.

Should you not have the dvd: Here https://youtu.be/5LBDnJv5B58&t=297s is the sharpmaker instructional film. I´d highly recommend watching the whole content, but if you just want to see the part about sharpening SE: It starts at 19:23 into the vid.

I will add a caveat here. If your technique with the Sharpmaker (or any other system including freehand) is bad enough, you can straighten the edge of a serrated knife. I have purchased used Spyderco knives that have had the teeth worn almost completely away. Used correctly, the Sharpmaker can restore those worn edges, deepening the scallops and bringing the teeth to more of a point. All it takes is patience and practice.

Thank you all.
I will watch and read all those post you recommended

[Wartstein]

Thank you all.
I will watch and read all those post you recommended

Hope you´ll share how it works out for you! :)

Two recommendations that helped me ( listed in the threads anyway, but still):

- Clean the rods frequently (since with SE you only use the corners with not much surface, they clog up pretty fast)
- Use light pressure, lighter than you might think!
