New recommendations for angle settings

We have discovered that the 21 degree angle setting works perfect on almost everything. When you are set at 21 degrees on a kitchen knife you are actually sharpening at about 19 degrees because you are resting on the FACE of the blade.

 

Chef's Knife face

 

You must be resting on the FLAT of a blade in order for the angles to read correctly.  The FLAT is the same surface that the handle is attached.  There is no FLAT on most kitchen knives.

Sports Knife flat

Almost all sporting and pocket knives are 21 degrees.  Often the FLAT is not large enough for a solid rest. Start a bevel at 21 degrees resting on the FLAT.  Move to the FACE of the blade, put some marker on the new bevel, and reset your PIVOT.  Now you will be set at a much higher angle, but you will be sharpening at 21 degrees on the blade.

Sports Knife flat and face

Exceptions:
  • Japanese cooking knives  - Set at 17 or 18 degrees. These are much thinner knives and can handle the lower angles.
  • Heavy hunting knives  - set at 23 or 24 degrees if you are unable to get an edge at 21.

    think this angle should be used for fillet knives? also, do you recommend using polishing tapes on fillet knives?
    Great tool!!!!

    Yes, when you are sharpening a fillet knife at 21 you are usually lower than on a chefs knife. So you would be sharpening at about 18 degrees on average. The narrower blade gives you a steeper angle drop.
    We haven't done an extensive test on the polished edge on fish but we have on meat. On that test the polished edge won hands down so I am going to assume it would be the same for fish. We have done cutting tests on many different materials and the polished edge has always won. It simply moves through any material easier and it lasts longer.

    Ben,

    With regard to kitchen knives, are you suggesting using the 21 deg. setting even though the knife is resting on the face and actually sharpening at ~19 deg.? Or are you suggesting that one should set the angle higher to achieve a 21 degree sharpening angle?

    Thanks, loving my edge pro.

    Just got my first EdgePro Apex and sharpened several Chef, boning, filleting, and paring knives, and am blown away with the stellar results (as anticipated). The uniform angle precision and grinding thru polishing steps are unmatched. I achieved edges like never before, except on a lucky day. Thank you. You have given me peace where frustration once thrived. I am truly impressed and grateful. Cheers . . . . . . P.S: Now I want Pro Model for bragging rights

    Thanks for the update. I am interested in your comment above about polished edges and using polishing tapes, as this seems to differ from the instructions i recieved in my apex kit. Are you saying that in all tests polished edges with tapes returned better results, hence i should use those tapes for all knives, including my kitchen knives?

    Matt, No, I am only saying that the jury is out on polished edges for fish. At this time we ar recommending that you only polish Japanese Cooking knives and sporting knives. All regular kitchn knives finish with a 600 or 1000. Use the knife until the edge starts to fade then use the ceramic. Use the edge again until it fades and use the ceramic. Continue doing this until the ceramic will not bring the edge back. The edge needs the micro serrations left by the stones and ceramic to cut through vergtable skins.

    Kelsey, I am saying to stay set at 21 degrees and put 19 on the knife.

    has anyone used this product much for woodworking tools? chisels plane blades axes that sort of thing.

    Yes, we do have many customers using the Edge Pro on woodworking tools. The Professional Model with the Scissor Attachment will sharpen chisels including your larger gouges, plain blades, plainer blades, scissors, including hair styling shears, pruners and loppers. It clamps vertically and horozantally so you can sharpen anything you can clamp. Then, if you want to sharpen draw knives or axes you would use the knife sharpener. You do have to do a little set up work for an axe.

    The knife sharpener will sharpen any knife.

    Hi Ben, Peter in Halifax and after almost four years I am still truly enjoying my Edge Pro Professional. I love you updated site and great video, I learned something new from it. I've sharpened many knives in the last 4 years Ben, I still get startled by the edges from the 15 deg Relief and 19 deg (set at 21) primary edge, still my sharpest knives.
    Thanks Ben
    Respectfully

    Will this work on single bevel knives like plant grafting knives? Thanks.

    I am confused by the angles. Is 21 degree ,or any other angle,per side, meaning a 42 degree included angle?

    Just out of curiousity, I sharpened a daily carry Benchmade 710 with D2 steel using my EdgePro Apex. I sharpened it to a mirror finish that was blah, blah, blah you all know how sharp. I hadn't touched it for over a year until today. The knife remained sharp enough to gut fish without any force or sawing even after camp tasks. Hands down, the best sharpener I've used. The Pro model is on my short Christmas list for this year (though the Apex is still getting the job done as well as it did when it was new several years ago.)

    Frank, We have sold a few Edge Pro's over the years to customers that were just going to do grafting knives and they were very happy with the results. With this system it is very easy to polish the edge and the polished edge goes through hard material with much less force than an edge finished with a stone. I think you will be very impressed. If you would like to see the results you could send me a knife and I will polish the edge and get it right back to you. Mail to Edge Pro PO Box 95 Hood River, OR 97031 Include a few dollars cash for return shipping.

    Regards

    Vijay,Yes, 21 degrees is 42 included angle. However this is only the case when you are resting on the FLAT of the blade. The FLAT is the same surface that the handle is attached. Often the FLAT is large enough to support the knife for sharpening but if it not, you just start the bevel on the FLAT, and then move to the FACE of the blade and reset to your 21 degree angle. Now you will be set up around 23 or 24 but you are putting exactly 21 on the knife. Then in the case of kitchen knives you are always resting on the FACE of the blade which lowers the sharpening angle. So when you are set at 21 on a kitchen, knife you are putting about 19 on the knife, which we feel is perfect.The exception is Japanese knives that are done at 17 or 18 degrees. Regards, Ben

    Ben, would you give us tips on sharpening uneven bevels. One knife I sent you had factory bevels on one side 22 degree bevel and the other 12 degree bevel. Can you give us the techniques to deal with this? Thanks

    Question. For chisels and drawknifes where there is a long primary bevel, do you recommend sharpening the entire bevel, or putting in a smaller secondary (micro)bevel at a steeper degree? If yes on the micro bevel, how much difference - half a degree, one, two degrees?

    Just received my Edge Pro. How do I sharpen the gut knife side of my Outdoor Edge SwingBlade?

    Frank,
    You just have to pick and angle that is a happy medium. I am not sure what I did with your knife but I would guess something around 18 degrees for both sides. Then if the edge is in the center of the knife everything will come out even. If the edge is not in the center of the knife you will wind up with a wide bevel on one side and a narrow bevel on the other. This is a completely separate problem and needs to be corrected slowly over time. Every time you sharpen the knife you should make two passes on the narrow side for every one pass you make on the wide side. It may take years but the bevels will eventually even out.

    Al,
    I always put on a smaller bevel but it is not a micro bevel. The only time I put on a micro bevel is when I use the ceramic hone on a kitchen knife. If you tried a micro bevel on the chisel or draw knife the edge would roll over. I usually go up 2 or 3 degrees from the main bevel and will give a normal width bevel.This keeps the angle very close to the original angle so you will not notice any decline in performance but you will get a slight increase in strength and you will be able to resharpen easily.

    Tom,
    You would sharpen the swingblade just like any other re-curve knife with the 1/2" stones. If you needed to sharpen it and you did not have the 1/2" stones you could still do it with the 1" stones and get a very good edge. It just would not be as perfect as it would had you used the 1/2"
