Some people say, it is not so difficult to cut a glass slide (0.8mm to 1.2mm thickness / plate) with pen-style cutter by hand. You may not need any support equipment in that case. You are probably right at a certain size of cutting if you are skillful with your fingers.

How about the situation of 2 layered glass slides’ situation?
Can you also do it by hand? Maybe yes, but probably no. You don’t have reproducibility, we guess. Especially the surface of the section, sometimes 1 plate looks OK, but another side is no good.
If you have 2-tier glass plates, you can cut them together with our Karate Groover.
Even if you can put “something” between those plates, you will get a beautiful cross-section again and again.
When it comes to sandwiches, this Karate Groover helps you a lot, for sure!

We will exhibit the polymer conference with our local distributor SIMS in Daejeon(대전광역시) in the midwest in South Korea in April. The meeting will be held from Wed. 8th to Fri. 10th. Daejeon is the 5th largest city in Korea.  There are many government agencies and research institutes. You could also see a lot of nature there!

We are planning to display a “Japanese” rotary microtome and several different types of knives.
This microtome is made for cutting hard materials samples and stronger than Leica and RMC microtomes for sure.
If you have any samples that you gave up to cut by microtomes before, you may use ion milling or polishing machines now, we suppose.
On the other hand, sometimes those methods take time to prepare but results are not so good. That is the reality.
If you can cut your samples by microtome, that is easier, faster and wider space you can see. Plus, the microtome doesn’t make heat during the processing.
If you have never seen this Japanese equipment, this event might be a very good opportunity to open your eyes.
Yes, it is possible to cut your own samples on site, if you want. Why don’t you bring it and do it by yourself.
Look forward to seeing you in Daejeon very soon!

We have never made an ultra knife with a big boat, however we had the requirements several times recently. That’s the reason we make this “SYM Grande” for fulfilling that kind of request.

This knife is probably suitable for the ATUMtome unit, if you have that system.
We have both 35-degree and 45-degree with 2mm, 3mm  and 4mm blades.
The big advantage of our Grande compared to the existing Maxi boat is our boat is bigger than the existing one.
The boat size: Length is 1mm longer and width is 2mm wider than Maxi.
If you can put more water into the boat, you will get more benefits for sure.

We are not sure the specific timing but we will change the box of our diamond knives shortly. Once the current model is out of stock, we will switch to the next model step by step. You will probably get a good feeling with this tiny variation.

The new case has a small window on the top and you can see what kind of knife is inside.
It is very useful to distinguish the knife without opening it.
Plus, we will prepare another color, “white” at the same time.
We are planning that black boxes will be used for room temperature knives and white ones for cryo.
Even if you have many knives on your shelf, you will reduce the time to search for an appropriate knife with this visibility.
Hope you like this window box!

We will inform you that Syntek will have year-end through New Year holiday breaks from Saturday 27th of December 2025 to Sunday 4th of January 2026. During this shutdown period, we will be unable to receive any deliveries for goods and services to us, Syntek. We will start both our office and factory again from Monday 5th of January.

As you might know, oriental countries have 12 different zodiac signs that are based in Chinese history.
The animal symbol will be taken over from Snake to Horse in 2026.
If you were born in 1942, ’54, ’66, ’78, ’90, 2002 and ’14, your zodiac is the “Horse!”
Horse is symbolized as “jump”, “advance”, “action”, “challenge” and “passion”.
Some parts of our life are still drifting on a chaotic sea of uncertainty.
You may feel “You can lead a horse to water, but you can’t make it drink.”
But, hold your horses. You may say, the old horse does not forget the way.
Everybody could make the right decision and find the best way, if you try it seriously.
We deeply wish you will have lots of wonderful times next year.
Let’s make a leap forward and higher place!

Good news for ultra-thin section researchers! Now the 10.0 mm ultra knife is coming to our regular lineup. We have not only 45-degree, but also 35-degree.

If you would like to cut wider sections, this knife will be the best option for you for sure.
We have already tried to cut the mouse brain at one of our customers in the USA.
*Section size is 5.5mm(W) x 10.0mm(L) x 80nm(T)
If you are interested in cutting results, can you see the video below?

It will probably be possible to create a wider blade like 12.0mm or more in the future…
