Unique diamond knife Vol.4: "GHP"- Patent Pending right now


We modified above MGH a little bit after we have got many feedback by its users.
Sometimes MGH is difficult to collect section(s) on the grid because you need to induce until the grid holder by yourself.
If you use this GHP, by the way GHP stands for Grid Holding Plate, no longer induce actions, because you will catch section(s) from the front side.
Once you set your grid on this plate, you just wait for section(s) to come to the grid. That’s it.
Section(s) is(are) jumped on your grid almost automatically. You don’t have to do any specific actions.
It works both 1 or 2 big section(s) and ribbons. Such a marvelous gadget it is!
You will get your section(s) by scoop method in this way. It means you can avoid wrinkles and breaks of your section(s) at the same time.
You would say this is the incoming item of MGH.

Unique diamond knife Vol.5: "Marking Knife" for serial sections


When you get many sections at the same time like array tomography, sometimes it is difficult to collect sections in the order.
Especially once ribbons are broken by accident sections are separated into many different directions.
You probably recover the order A to Z on your computer, however if those sections have a tiny spot(mark), your serialization task will be easier and faster than nothing.
This marking knife makes the above actions true. Don’t get lost anymore. Just go straight ahead.

Bits of knowledge for superstitions

Some people are believing, or they are believed, diamonds of all diamond knives are made by natural stone.
Basically, we don’t want to say things that will shatter their dream.

On the other hand, we also have a duty to tell the truth to all users.

If you are told “Our diamond is natural” by your provider and your knife width is 3.0mm or more, you would better to doubt about that information.

We do not say the stone is synthetic (artificial / man-made), but if you create wider knives(means more than 3.0mm), the raw stones may cost more than your purchasing price.

Or that maker selected very low-grade raw stones.

<pIt is possible to produce natural diamond knives from Syntek, however it will be 2.0mm or less if you considering the current market price.
Our raw stones are selected top or second top quality grades.
That might be one of the reasons, nevertheless you should be careful.

Please see the details are as below.

Is your diamond really natural...!?
