TSProf K02 sharpens knife to BESS 20 edge (record setting)

I agree with what everyone has said and my point was not to make it sound like I was bashing the TSProf products.

I also understand the person who did the test may not have every sharpener to run the same test with each sharpener and the same knife and stones but to me it is something for TSProf brag about yet but to me until that test happens they are more like an interim champ in the UFC witch many call including myself a Paper Champion.

Again to be clear I own a TSProf and love it but it will never be king until that test is done why because I guess then.

I'm the worlds greatest knife sharpener you see I got a brick and a leaf spring from an old pick up truck and did nothing to the leaf spring other then grind it back and forth until I got an edge on it now it's the worlds sharpest or at least until someone else does it and proves me wrong.

Ps, I too would like to know what abrasives were used.

We've held several sharpness contests across Australia during knife shows. People in these contests sharpen freehand and with all sorts of guided systems, and the champions use the TSProf - one knifemaker (Peter Bald) repeatedly scored 25 BESS in 2 separate contests, and Nathan shown in the beginning of this thread 20 BESS; the sharpness was measured by different people on different BESS sharpness testers. 20-25 BESS is twice as sharp as a disposable shaving razor like Gillette.
I am only telling the impartial facts, I do not own a TSProf myself, but if I ever want a guided sharpening system, I will take the TSProf because of what I witnessed in these sharpness contests.

When premium knife owners in Australia want their expensive knives sharpened, they send them to either me or Nathan with his TSProf. In his YoutTube channel Nathan has full detail sharpening from start to finish that can serve as an instructional video on using the TSProf.

The one above is Kigami Yellow paper steel.


This one is Shirogami, takes and holds a better edge.

You are Pavarotti in hand sharpening .... :thumbsup: Did you make some cut and then test sharpness again ? It will be very interesting to see how long last that laser like edge ?

You make a good argument about the importance of the other elements, among them the abrasives used and the technique of the person using the equipment. But, I think the sharpening device deserves a lot of credit much like in car racing, there is considerable credit given to the car, when we know that it's a team effort of driver, pit crew, tuning and tires as well.

So , why sharpening device deserves a lot of credit ? Can you explain that ?
 
I like a more aggressive edge, The push cutting is nice but the draw cutting is diminished. It's just Kigami steel so it's nothing wild.

The BESS tester doesn't tell you what is effective for all cutting uses. Sharpeness and cutting effectiveness can be different things. Selection of proper edge finish for the cutting task at hand or just preference overides the lowest value.

Unfortunately as these testers became more popular I see that becoming lost in translation and for some they will be lost as to why they see lower cutting performance for some tasks despite the lowest BESS.

I do like the BESS tester though. It measures the classic definition of "sharp" and the BESS Media is thick enough to rule out fragile foil edges in most cases.

It's a useful tool in the right context.

I enjoy reading Vadims work with the BESS tester.

Vadim,

Nathan would be a good sharpener with or without the Tsprof.

It is nice to have a Cadillac though for sure.

The difficulty is getting rid of the fine burr without crushing the edge underneath.

Has nothing to do with a fancy system or robots. :D

CBN helps though :p
 
I think most people just give up on freehand sharpening moreso than failing due to lack of ability. It’s really not that hard. What IS hard is translating written descriptions into practice. I think I could have learned in a fraction of the time with a live expert by my side, apprentice style.

That's the best way to learn. Hands on, I try to teach on the side at every knife show when selling my custom knives.

Taught this gentleman at the Eugene show.



I don't really get into the finer details about burr removal at the show with beginners, I try not to overwhelm them and give them a small victory cutting paper.

Honestly, this doesn't have to be about freehand vs fixed angle, both work.

Like the old argument of forged vs stock removal knives.

My personal preference is for freehand but one can't ignore the unique advantages each offers.

I have an Edge Pro but I'm not the most experienced with it but I'm a big fan of Ben and Cody.

@Diemaker made a beautiful edge on a Maxamet folder I let him borrow to play with.
 
I don't think George is trying to say that if you use a guided system that it's the guided system and the guided system alone that deserves all the credit,but the point is if a guy had the best engineered guided system hands down what's the point of producing it if your not going to be consistent when making them,or what's the point of taking that perfectly designed and engineered guided system and drilling all the holes by hand and so on.

I think you could get the same sharpness from a Edge Pro or Hapstone if not a sharper edge with the same person knife and stones just because if you use the clamp's vs a table because you've got flex from the springs.

But I can also understand why the TSProf's are being used so much and for me I feel they are very well made and they have a lot of clamp option's as well and they are a very smooth operating system and built to last.

DeadboxHero DeadboxHero When I seen this I was wondering did you make a CBN stone of your own to try.(BBB 1000 grit Vitrified CBN stone)

There are 3 testers in the world that quantify sharpness: the US BESS Edge Sharpness Tester for $179-259, the New Zealand Anago for approx. $20,000, and the UK CATRA for approx. $50,000 - 80,000. For a small-scale sharpener the BESS Edge Sharpness Tester is the only feasible. Only a few of the larger knife making factories use the CATRA testing, while the Anago is used by several makers of the industrial knife sharpening equipment.

Of all 3, only the BESS Edge Sharpness Tester evaluates both sharpness and keenness and can tell about sharpness in the razor range.

CATRA can not be used to evaluate the edge sharpness, because the edge is abraded beyond shaving sharp in its 1st cycle; the edge gets practically dull by the 4th cycle (can't cut print paper), and the full test includes 60 cycles. CATRA best evaluates role of the blade geometry and the steel wear resistance in the cutting ability.
The NZ Anago evaluates the edge sharpness, but not the keenness.

My old "Edge Inquisitor 3000" in its final incarnation was able to measure dulling pretty accurately, both pressure and draw cut.

For pressure cut it was accurate to within half a pound of pressure or less (I didn't have a reliable way to add/remove less than that.

For draw cutting it depends on initial edge sharpness, but 10lbs of pressure on a draw cut seemed to work for all reasonably sharp knives. You could go lower, but the knife has to be extremely thin and sharp, and not very important anyway as you're measuring edge degradation, not dulling. Most knives tested can still shave armhair when done.

All testing done with 3/8" Manila

Am rebuilding the clamp and it will back in action in the next couple of weeks.

Anyone has any interest in running some knives on it let me know.
