TSPROF K03 users?

Thanks! And yeah, the "Classic" kit comes with the fine tuning adapter.

Ah, good. I see the "classic" version comes standard with it yes.

Not sure if you have one, but make sure to get yourself a digital angle cube too. At a push, you could use your smartphone with an app, but it's much nicer to have a magnetic angle cube.

Let us know how when you've received and tried out your R2! I'm confident you'll love it.

Gosh I hope TSProf doesn't also go on sale now too and I end up with both. FML. hahaha

Looks like your prediction / fear about a Black Friday sale came true. I just woke up to see some epic discount codes on Gritomatic for both Hapstone and TSPROF systems.

TSPROF's shop is also offering some great BF discounts.

 

[matto6]

Yeah I saw those tsprof sales Wednesday. I ended up ordering one, canceling it and ordering another. But they didn't properly cancel so both are in the mail. So I'll now have 3.

I'll either return them, or sell them here for people who missed the sale.

Lol, that’s funny AF. Well, maybe not to the wallet, but from my side it’s funny. I’m out of town visiting my sister and ran into a Grizzly Industrial tool store , so I’m coming home with a 1x30 belt grinder, angle guide belts and strop belt too. So I guess I did my damage too.

So I received sharpener #1 of 3 - the (well, one of the) TSPROF K03.

Question #1 is - is it my imagination or do these whole milled clamps suck? They don't seem to have any way to adjust the angle that it grips the blade, so if the blade's grind angle doesn't perfectly align with the clamp's natural angle you get all the pressure along one edge. With my Spyderco Manix 2 the pressure is all on the back of the knife blade. Below is a video to show the wobble that remains even after I've tightened it snug.

Do people use some sort of rubber padding in there to avoid hotspots? I'm a little surprised I should need to do this with the rolls royce of sharpeners.

The Hapstone R2 Classic that I ordered has adjustments on the front and back edge of the clamp so you can control the angle. Is this round 1 to the Hapstone?

Use one clamp on the flat tang area of your knife (to stop rotation/wobble), and the other clamp on the spine closer towards the tip of your knife, maybe an inch or so from the tip (to stop flexing). Using most of these systems this way gives the best results.

If the blade is short enough or rigid enough, just one clamp on the flat tang area may be enough. This will depend on the knife.

No rubber padding is needed, just make sure your blade and clamps are clean and free of sharpening swarf/grit particles before clamping. The aluminum is a lot softer than your blade steel, so it can't scratch it. Aluminum oxide/Silicon carbide/diamond/CBN/steel swarf between the clamp and the knife WILL scratch your blade, so just make sure it's clean before clamping.

Interesting, thanks for the reply.

So when I do that, the clamp on the tang has all the pressure on the front edge of the clamp, since the clamp has some angle built into it. So you end up with one clamp having the hotspot on the end of the clamp, the other having the hotspot on the back edge of the knife, and they do indeed balance out to preventing rocking. But man, eww, this doesn't seem icky to you? It looks like so much clamp is on the knife but in reality it's only touching along two fine lines.

This works better than an adjustable clamp because the adjustable clamp flexes more?

Yes, give it a go and you'll see how well it works. With most knives this method will be stable as can be with no wobble at all. This is part of the reason why these systems are designed with 2 clamps.

As for the adjustable spring steel clamps, yes some of them do work well too align with the grind of some knives, but not all knives. Both TSPROF and Hapstone offer spring steel adjustable clamps but using it the way I described still works best, even if you have the adjustable spring steel clamps.

If you really want to follow the exact grind of every knife you have, you'll need a bunch of different clamps. KakBritva offers lots and lots of clamp options with opening size and cutout angles (have a look on Gritomatic). Gritomatic also offers Gearconnect adapters to use these clamps on other systems.

But honestly, you don't need to do that. If you clamp your knives the way I described, you'll find that it works very well.

I just sharpened 2 knives with the TSPROF, and this thing is outstanding.

I love being able to use the angle cube between each stone to ensure the angle hasn't changed. And adjust the angle easily with the dial. And the spring-loaded stops on the arm so that I don't accidentally go too far in either direction while sharpening. And the nice wide clamps that hold my 10" kitchen knife with no problem.

I'm not sure I need to open the Hapstone R2 box. It probably gives me most of the above, but the TSPROF is so solidly built I don't see why I wouldn't keep it.

I still think the non-adjustable clamps might give me trouble for certain small knives. And I don't like that I can't place them dead center when needed, so I may end up buying the center, angle adjustable clamp. But I'm fine doing so if needed.

Yep, the K03 is a great piece of kit. Pricey, but worth it!

Don't write off your Hapstone though, seeing that you have one now, give it a try and if you don't want both then sell one of them after if you have tried them both for a while.

You could always buy some Gearconnect clamp adapters for your Hapstone angled / center clamp to use them on your K03.

I have both the spring clamps and the milled and use them both as needed. I used plasti dip on the ends of the milled clamps for blade protection and grip. I have no issues with blade movement. I also used the plasti dip on the spring clamps, more so for rust protection and blade protection. You don't need both types of clamps, but it helps.
I went to the K03 and KADET after years using Wicked Edge and for me, it's been a game changer. You're really gonna fall down the rabbit hole, as I have, with the K03.

Thanks.. I like the plasti-dip idea, but how durable is it? It doesn't get torn up where the edge of the blade and clamp meet?

Which additional clamps do you have? If I don't keep the hapstone and use 777 Edge's Gearconnect clamp adapter idea, I'm thinking of getting this TSPROF clamp for when I want a smaller knife more centered.

Be careful with a rubber coating or pad on your clamps. If it does get contaminated with, let's say diamond powder, and you clamped the knife with the swarf or powder on the clamps, the grit can embed itself deep into the rubber and you may not be able to clean it out. You could end up with a clamp that will then always make haze / tiny scratch marks on your knife, and you'll have to completely remove the coating to get them clean. (Depending on the rubber / silicone type.

If you use the clamps correctly and keep their insides clean, you really don't need any coating or padding.

Great point. I'll keep them naked, and ensure both the knife and clamps are clean before each usage.

This version (fillet) of the TSPROF clamp will serve you better with small and thin knives. And if you don't keep the Hapstone, you won't need an adapter for this clamp.

The Gearconnect adapters are meant for different branded clamps other sharpening systems. For example, a Hapstone clamp on a TSPROF system, or a TSPROF clamp on a Hapstone system.

I was looking at that one but it says "We do not recommend to use it for knives with a spine thicker than 2.5 mm." Some of my kives (such as the Small Sebenza) have a blade that is 3mm thick. The Umnumzaan is 3.5mm thick. I figured it's a bad idea to overdo it?


Regarding the Gearconnect - yeah that all made sense. It think my wording was just confusing.

 

[777 Edge]

Ah, Gotcha right. I was assuming you're planning small and thin blades like Victorinox etc. In that case the regular clamp would be fine.

 

[NorCalQ]

Actually, I haven't had any issues with grit in the coating of contact surfaces. Seems once the clamps are set, no grit gets between coating and blade surface. Also, no issues with the coating tearing. No doubt, the coating will wear thru eventually, however it's very easy to peel off and replace, so no worries there. I was using tape on the blade, but that wasn't working out well, as the tape would become soggy. The single and double fillet clamps are steel and have shown rust on occasion, so the plastic coating has worked out well for that. I was a doubter, until I tried it.

I sharped 5 knives on the TSPROF now and it's great.

Before selling the Hapstone I took it out of the box to confirm all the parts are there, and checked out the design. It's really pretty nice! And it has one thing that I think is nicer than the TSPROF which is that the bushing that the arm travels through has ball bearings so it's sooo smooth. The TSPROF isn't bad, but the R2 is smoother.
