EP evaluation thread for Knifenut1013

How would you sharpen a double edged sword with a ~40 inch blade by yourself on an EP?

The hardest thing about sharpening a double edged weapon is keeping the blade parallel to the base, not the length of the blade. To achieve this with the EdgePro, you put a small plastic clip onto the blade stop.

This clip is the 'clamp' that is used for Document binders; the sort where you have a folded plastic cover, you put your papers inside, then slide the clamping spine over the outside of the folder to pinch the cover and the documents in place.

My EdgePro shipped with one of these, but I long since lost it and replaced it with a piece I picked up in a stationary store and cut to length. When this clamp is spread over the blade stop, the back edge of it forms a concave trough that holds a double edge blade quite well, keeping the blade nice and parallel to the base. It's not as accurate as having a flat surface of blade lying directly on the base, but so far I haven't found it to be a problem. While I haven't sharpened any 40" swords, I have sharpened quite a few double edged daggers. They got pretty sharp. :thumbup:

I suppose that if the edge clamp didn't work for a double edge sword, one could always just cut a small wedge to put under the back edge...

Nope, but good question. As you note, if one were to sharpen further away from the pivot point the bevel would change. This is a drawback to most clamp systems. To avoid this happening you'd have to re-clamp every inch along the blade. But with the EdgePro, the blade is always free to be moved from tip to choil (or the other way if you prefer) so you can keep the stone always moving at exactly 90 degrees to the edge if you wish to be that precise. No need to pivot at all.

In reality, when sharpening most blades on an EdgePro you never allow the stone arm to sharpen off the base. At most there can be an inch or two of play either side of true 90 degrees. The resulting bevel probably wouldn't really be noticeably different on anything but a micro level. But if one desires a 'perfect' bevel, it's a simple matter just to keep the arm completely perpendicular to the edge while sharpening. Not difficult at all.

Understood, thanks, but if you have a blade with lots of belly, how can the system compensate for that type of changing angle?

The same way that you would do it with a Sharpmaster. You rotate the blade. In this case, you'd set the blade stop a bit further back to give you the room to do the turning. When I sharpen a knife with an exceeding large bevel (I'm talking 'pregnant') I sharpen closer to the side of the base rather than in the middle, just to make this easier to do. Sorry, but it's actually easier to do than to explain! :o

The idea is to always have the stone moving 90° to the edge, just as with the Sharpmaster. Anything else will result in differing bevels. Consistency is always the key in sharpening; stone across the edge, stone above the edge, pressure of the stone on the edge. The guided systems just make maintaining that consistency throughout the sharpening process easier.

Greetings: A short boring story of why, I feel. the Edgepro is excellent at addressing my needs. In the mid to late 1960s, I worked summers as a counselor at Ten Mile River Scout camp in NarrowsBurg NY. For three of those summers, among other tasks, I gave presentations on wood craft and camping from late June till Late August to what seemed like thousands (really hundreds) of campers (all Boy Scouts). This included, among many other things, knife and hatchet maintenance. My enthusiasm was good, my sharpening skills were not. This camp was operated by the Greater New York City Boy Scout Councils. At least 95 percent of the scouts were New York City boys, an area not noted for it's vast wood crafting opportunities and a tradition of outdoorsmanship. For many this was their first opportunity to use a knife or hatchet on anything other than a popsicle stick. Among these city boys, there were a few, who after my brief demonstration on the nuts and bolts of sharpening, were putting edges on their equipment that were embarrassingly superior to mine. I suspected these boys had previous experience in sharpening. Nope. Questioning revealed that this was their first, or at best, maybe third time sharpening anything. My conclusion then ~ these kids are making me look bad. My conclusion now ~ some people are naturally better at sharpening than others. Practice can improve results but only to the limit of personal ability. Can't be good at everything. My grandfather, a cabinet maker, could put outstandingly sharp edges on his knives and tools using three oil soaked bench stones that were so badly dished they could be used as soup bowls. My father, his son, could not. Fast forward to today. IMO, whether a novice or expert sharpener, there are three primary PERSONAL components involved in sharpening: Technique, practice and talent. I can study techniques. I can practice for years. But talent still eludes me. Not unlike why some knife makers are amazing artists and artisans while others are good but they are not great. It appears that free hand sharpening is a combination of art and science. I don't possess the art but I can utilize the science. My cooking sucks but I still enjoy a good meal. My sharpening skills are not the best but I still appreciate a keen edge on my knives. Enter the EdgePro. Although my skills are minimal, the EdgePro is, in my experience, the best readily available method or system that allows me to get a very sharp edge on every blade I've sharpened. I would not be foolish enough to attempt to compare my limited knowledge and ability with those of KnifeNut1013 nor hope to compare my posts with his substantial history of contributing to this forum. However, I see the Edgepro as a tool which allows me to consistently approach the level of results that he and others can produces by their personal talent and abilities. It lets me get an Edge like a Pro. IMO it works fast and well. Hence it's popularity. I'm still working on using my bench stones and other systems but as of now, the Edgepro gives me great results without frustration. OldDude1

There have been several concepts presented on different forums that I have not as of yet been able to fully grasp and understand. THIS is the most recent. Can ANYONE explain, in simplistic terms, what is being referenced here ? Is this wear cosmetic or structural or what ? Is it easily visible or only observable at the microscopic level ?
 
Ever consider selling it? There are plenty of folks who'd love a good deal on an EdgePro. Why not get your money out of it, rather than let is rot in the shed?

Because I modified it to better suite my needs and I'd be lucky to get 50 bucks out of it. Plus I do keep the stones in my shed for the occasional quick touch up of a garden shear or what have you. And before you start in on the mod making it not perform as it should. I simply connected it to a base so that I could use small clamps to hold the blades in place. Not being able to lock the blade in a fixed position IMHO makes the Edge Pro quite clumbsy. But then again as I said I was using it mainly for reprofiling so it was a plus for me to be able to lock the blade in place while removing large amounts of steel. I'm talking about taking a edge that was probably 25 degrees on a .25" thick blade and laying it down to about 15. So the amount of metal needing to be removed was substantial.

Listen if you like the Edge Pro more power to ya. I'd never tell anyone how they should spend their money. But from my experience a $200 manual sharpening system with stones that need constant training or replacement compared to a $210.00 kalamazoo 1X42 bench grinder is a joke IMHO. Just the way I see it. I've used both and found the Edge Pro wanting.
 
You're comparing apples to oranges, a bench grinder to a hand powered jig.

And what is wrong with comparing apples to oranges? If they cost the same, why not buy (or talk about) what you prefer? I think it is a fair statement, perhaps a bit off topic but technically we are all off topic. The only one who is even supposed to post here is Knifenut.
 
unit,

That part of the thread is pretty much over, so please don't try and dredge it back up.

Thanks

Most of the knives that I have seen done on the EP were done by my son and 99 percent are pretty spendy chefs knives. On these, the EP is the perfect sharpener for anyone who can't hold the exact bevel while hand sharpening. I sharpen my Kitchen knives mostly free hand but every now and then I take them to his house for a real good new edge. He has diamond stones for his to get the rough work done quick then goes to the water stones and other stones that I have never even heard of and can't began to afford.

He is a chef and does all of his knives and most of the other employees knives.
On short blades with up sweep edges, it may take more work that it's worth. But then he is used to large long knives and has done many hundres of them.

Your arms are a lot longer than mine, or you wear cut proof gloves :). Also, I do not think I could accurately sharpen the tip with the hilt hanging four feet away with all that leverage on my left hand while moving the stone with my right.

I don't think there is a problem with someone saying "I like apples better than oranges." He doesn't care for the EP. I, having never used it, still agree, because I personally don't care for any kind of jig when I sharpen. I like the "zen" feeling of hand sharpening to a razor edge, using only my skill and talent, and an angle jig doesn't do that for me. That said, if someone else prefers the EP over every other system, more power to them. However, I can take my skill, and use a smooth river rock, or a car window, or the ceramic piece from a pool heater like I have in my pocket, and keep my edges sharp. I don't feel that the EP gives you this kind of ability. I could be wrong, though.

Oh, and I prefer oranges...

No I'm not. I'm comparing two sharpening methods that both cost nearly the same. Yes they are apples and oranges in construction. But the ideal is equatable. If you have $200.00 to spend for your sharpening needs. The Edge Pro is a waste of time and money. For $200.00 you can get yourself a belt grinder or some of Richards buddy's fine paper wheels and a grinder. Both of which FAR exceed the edge pro's abilities. I'm not so much comparing the different devices as I am their prices. The Edge Pro at $50.00 would be the greatest thing for the inexperienced sharpener who needs a jig driven sharpening kit. But at $200... you can start getting real equipment.

I would like to request some clarification on this statement. I am not sure what exactly you are trying to limit or accomplish at this point.
 
Like I said before, I personally use a variety of equipment, all have their pros and cons. While in general, someone using an angle controlled device will get a better edge, there are of course exceptions to the rule. In addition, I'm sure those that gravitate to a sharpening forum, will invest the work needed to refine this skill, and put an edge on a knife that's as good as or better than what a device will do.

One thing to keep in mind with powered equipment, is the metal dust that is created. I ran one for a time in a spare bedroom, and ran a powered air cleaner to filter the air. I thought that was fine until one day i noticed a collection of metal dust on a magnetic alarm contact in a different room. So it's something to think about.

I think it's great to compare different sharpening methods, not for which one is better or worse, but for what they can accomplish. For example, if you handed me a knife with a broken tip, I would use a belt sander. Hand me 20 knives to do in an hour or so, I'd flip on the Sharpening Wheels. To put the best edge I could on a knife, I would use the Edge Pro, or maybe the Sharpening Wheels. To put a great edge on a knife and feel good about doing it, freehand. There are other factors in all this, it's just some examples, and others will see it differently. Even I might, depending on the situation.

I obviously think the EP is a quality sharpening device and worth the money. But I don't think it's the "best" or that it meets everyone's needs. I've recommended a variety of methods in threads, that I try to base on what a person is looking for, and their situation.

I totally agree that, if you have the time and desire to learn freehand sharpening, it's definitely an asset and more flexible process. This isn't and never was a "which is better" thread. I'm not sure there is an answer for that. It's simply a question of which method fits your needs.

Me neither. Instead, I'd pile up some large books to support the hilt while I worked on the tip. One NYC telephone book would do it. But I've been pretty lucky... most of my friends have their swords sharpened between campaigns at the local armorer's shop. :D That leaves me all the 'Main Gauche' to sharpen. MUCH easier!! LOL!

When I have to change a flat tire, I don't try to lift the car myself. I use a jack. :thumbup:

I just don't see all the fuss. I especially don't see how you get the extension cord all the way out in the boonies to use your electrical device to sharpen your blade. You need to be able to sharpen with a stone out there. It worked for hundreds of years.

You don't. You just plug into a nearby current bush... (rim shot! ) :D
