Sharpeners Manko-LOBSTER (new knife sharpener)

[Man'ko]

Greetings, I present to you a slightly different device for sharpening knives. Professionals are kindly requested to give their comments regarding this system. Sharpening a knife with a constant angle along the entire length of the blade of any geometry.

Lobster
Sharpener designed for professional sharpening of knives, scissors or any other cutting tools. Due to its compactness it can be used by the professionals who make money with this craft, or those who just love sharp knives at home.
1- The main difference of this system from others is in the hinge with which we regulate the sharpening angle. The Hinge, after we have set the sharpening angle is locked, but has the freedom of rotation around its axis and the free movement vertically. Limitations and position of the hinge on the vertical axis is set by the geometry of the blade, and he always keeps the same angle.
2- Once the specified angle has been set, we can work on our sharpening to the end, for instance, when replacing the abrasives, calibration is not required in thickness.
3- The ability to control pressure of abrasives along the cutting edge till 0.00 grams (we can place the abrasive above the cutting edge and slightly press it to increase force in the transition to the tip of a knife. Reducing the pressure on the abrasive the spring lifts it accordingly).
4 With the micro elevations mechanism you may quickly find the correct angle very quickly and accurately
5- The sharpener supports sharpening on the table or on the claws with its changing mechanism

I'm not crystal clear on advantages vs edge pro, but Scorpion would be a far more fitting and marketable name.

Good call.

"Scorpion" or "Scorpio" would be a much better name. It certainly looks like a scorpion. And a scorpion logo would definitely look cooler than a lobster logo.

Of course, the name doesn't mean squat if the device doesn't do a good job. If you (Man'ko) are the inventor, then I wish you the best of luck.

It does look interesting. But unsure how it would not require fine tuning with stone thickness, just like any other bar/rod guided system.

If I picture it correctly....The knife is in a fixed location on table or in claw. The angle is fixed by the rod, with the first stone in place against the knife edge (at whatever distance it's set). So now the knife edge is in a fixed position, and the rod is in a fixed position, any stone thickness variation is the only variable that could throw off the angle. Unless that big round hinge is somehow cammed or geared to adjust elevation on the vertical rod with every guide rod movement.

The all metal version certainly does look more robust than the standard EP, but guessing it's just a prototype. I would venture to guess that unless it landed in price between the EP and WE (or much lower), it would be a hard sell.

Looking at the video, the angle seems to change with the vertical movement of the pivot; surely must produce a convex edge?

 

[Nomo4me]

I like the apparent quality of this unit, and it seems the pivot (hinge) function could easily be designed to lock/unlock depending if one wants convex bevel. Still not clear on how the clamping mech works. No matter. I have more sharpeners than sanity would suggest.

Doh, I missed the video links. I'll take a look at them later. Maybe I'm totally off. Wouldn't be the first time.

Very interesting, very adjustable.

Looks like a steampunked Edge Pro.

If I see it correctly, the stone arm moves up and down freely on the vertical arm but it does not pivot so the angle stays the same. As long as the edge of the knife and the stone stay in the same plane, the edge angle will be constant.

In the first video, the front of the stone appears to be rocking up and down with each stroke. Am I seeing things?!

That was my first impression as well but looking at the second video I got the other idea.
Would be nice if Manko explains the technical details.

Yep, adjustable from very round convex, slight convex and flat.

 

[Man'ko]

If we want to reach a convex edge, i think that in this type of sharpening the fact that it is slightly moving doesnt create significant problems. In this type of sharpening we are applying a lot of pressure on the whole mechanism that is why the is slight rocking. In order to eliminate this, much thicker central rod is needed. The question is do we realy need this?! For straight edges system stabilizes and there arent any rocking.

Let me tell you a bit more about this system.
Lobster is similar by its looks to EP, but it’s a completely different device.
On this device the sharpening is being done with the constant (same) angle along the whole length of the cutting edge regardless of its geometry. The angle of the sharpening stone is set by the hinge. The hinge itself can be lifted and lowered vertically by a special made spring. While sharpening any cutting tool we place the sharpening stone on the cutting edge and regulate the pressure against the edge whit the micro-elevating mechanism, this is really good for sharpening using more rough stones, for the finishing touches we place the stone above the cutting edge and slightly apply pressure on it with our hands in order to achieve the best results, and the best quality of sharpening.
If the thickness of the stone while changing is pretty much the same, then there is no need for any changes or regulations in the micro-elevating system, the spring will compensate any slight differences in thickness. If the thickness of the sharpening stone while changing differs a lot we can easily regulate the position of the hinge vertically. This system offers you the ability to absolutely control the pressure of the stones against the cutting edges of any kind, this is especially significant in finishing touches where there is a big risk of ruining the whole work if the pressure is to high.
While working on the table, there are three stabilizing planks in order to keep the same position of the knife when turning it on the other side, also on the center there is an additional bolt for fixation in order to achieve maximum stabilization and movement prevention (a really practical thing, especially when working with convex blades). On the top of all that there are two powerful magnets with force regulation and easy detachment. There is also a possibility of sharpening by moving the knife, the knife can be moved around its central point of fixation while the angle and height of the stone are set in a fixed position.
Taking in consideration different geometries of blades, all of the above is needed in order to reach top quality sharpness.
Almost forgot, my system can also work by Apex principle – with an option of increasing the sharpening angle along the cutting edge till the point of the knife. (By unfixing the hinge and regulating its heights on the vertical pole without the spring).
System also allows you to work with flipover claws mechanism where we fix the knife one time and work with it till the end of sharpening, the claw can be flipped over for changing sides of the knife without removing it from its fixed position.
The system works flawlessly and is able to meet the highest requirements of professional sharpeners and also allows amateurs to sharpen their tools on professional level.

Looks cool. Plus all metal is :thumbup::thumbup::thumbup:
