The Convex Knife Grind Fully Explained. The Ultimate Knife Grind

This is a more in-depth and detailed explanation of the merits and superiority of the convex grind (done properly).
It is the best grind.
This video is 25 minutes long and I dont have a teleprompter and had to prepare and think while speaking so if there are some mis-spoken words etc then LIVE WITH IT. thanks

Easily proven with science or a decent knife. Makers might not "make" it the best.. but if we are talking about perfection. then it is the most perfect form in the universe and works the best.. anyone that says otherwise has only used a pathetic and poorly formed convex knife and compared it with a better built "other" grind.

Many will disagree.. Many have finacial motive to disagree.. Thats fine.. I'm not saying that all the other knives out there are not Stellar, and better than you may EVER need.. I'm just saying that if it was made as an equal quality convex it will do the job better.. There are no exceptions.

My experience with knives is really limited to kitchen cutlery, but what you say here makes complete sense! Thank you very much for explaining this! I'm going to have to see about getting a good convex ground knife somewhere and testing it out :)

@Dwatthaell Can be hard to find. many custom makers convex the edges, but make the bevels flat. KnivesFishWild said his Japanese knives are convex ground. They look excellent quality if you check his videos.

Finally....someone with balls and brains....to marry fundamental scientic principles to the art of knives. Such videos renew people's faith in the knife business...tells us that our beloved knife world will not be held ransom in the hands of self proclaimed gear-reviewers, custom knife makers with self-taught (read debatable) scientific knowledge and advertise-pumping corporates. The video reaffirms that free intelligent men are out there. Thanks for deciding to take some time out to do this.

@Lonewolf25071 Thanks for watching and commenting.

Agreed it is tougher and cuts with less friction but we are talking on such a microscopic scale, creation of the bevels and maintenance becomes the key issue. This is not what you buy in stores folks as a convex. Creating the type of bevel you showed accurately is nearly impossible, therefor while what you are saying rings true it really is not practical for a knife that is used in any fashion. A preferred edge for knife users would be a flat grind that is stropped convex.

@dannyrexknight Sorry, but what I am saying is accurate, and every knife I supply is convexed in this fashion. in some cases you are right and the difference may be negligible if the flat grind is done correctly, but in a large number of cases the differences are very easy to behold. convex knives are not difficult in the slightest to maintain. the key is to not get caught up in the numbers.. thats not important. you adjust based on performance requirements.. not numbers.

just convexed my boy scouts of america slipjoint and i love it

What I gathered from this video is that convex achieves a thicker edge with a thinner spine. (edge and spine are the wrong descriptions, but you know what I'm saying) This accomplishes a stronger edge, while reducing slicing friction. It's the best of both worlds. Sound right?

@cooksecurities the harder you push the faster you wear out the stone, and the more metal you remove. light strokes are normally better.

@BigDumbJerk do you think they had sandpaper 500 years ago? convex, like any shape, can be formed on a stone. had you watched the video this would be evident.
