Some people have mentioned the safety of our Metalica because the blade part is exposed. If you take care of it carefully, it is hard to get injured with the edge of both ends, we estimate. Even so, we have to value those voices from the users’ side. After we considered how to materialize those requests, we succeeded in covering the sharp parts.

As you might have realized, once we cover both ends of the blade, you cannot use those parts for trimming(cutting).
Yes, it’s true but this is the trade-off relationship between practical and safety.
Protecting employees from external wounds is one of the most important precautions of your organization.
If you don’t need to worry about unexpected injury, you may say this is an “easy-to-use” knife.

We made a new shape of Metalica recently for trimming. As you can see in the left photo, it has a 45-degree diagonal on the right and left side. Those parts are available to cut blocks the same as the flat part(2.4mm width) in the center. Means, it would be a great alternative for your current tools.

As you might know, this Metalica is suitable to trim the resin blocks.
It is possible to use much longer time than glass knives and the sharpness of the edge is much more stable than glass.
Of course the price is lower than the diamond trimming knife.
It means, you just need it for trimming, don’t you think?
Plus, this knife cuts the semi-thin sections between 1 micron to 20 micron thickness.
You may say “Adios!” to your current trimming tools and try this Metalica-Diago!
This is a very handy, useful and sustainable tool for your sample preparation for sure.

Our knives have tried to use many new observations so far. We will introduce some of them below. Each article is very impressive and they are worth reading. You will probably get a new method of using knives especially with our characteristic models like MGH, JUMBO with steps and Marking needle. Of course normal types such as for room temperature and cryo work well, too. It would be great if you have new ideas from some of them.

We will let you notice the others later!

We will inform you that Syntek will have year-end through New Year holiday breaks from Saturday 28th of December 2023 to Sunday 5th of January 2025. 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 6th of January.

As we explained previously, we have 12 different zodiac signs that are based in Chinese history here in Japan.
The animal symbol will be changed from Dragon to Snake in 2025.
If you were born in 1941, ’53, ’65, ’77, ’89, 2001 or ’13, your zodiac is the “Snake!”
Snake is symbolized as “rebirth”, “infinite potential”, “perpetual youth and longevity” and “economic fortune.”
Many people are still not sure what’s going on around the world right now and where we are going exactly.
Even so, let’s conquer all difficulties and go up higher from our current position.
We really believe the best is yet to come with you.
We hope you will have a lot of good times next year, but take head the snake in the grass.
Talk to you soon and have wonderful holidays!
Very best wishes from Tokyo,

We will inform you of our new techniques for making tiny edges of the diamonds. If you have stylus profilers for measuring surface roughness or tracing the desired path of materials, our technology is suitable to you. We will probably create the stylus for the top following your demands.

The measurements always need to be repeatable, reliable and accurate, as you know. Of course, the measurement quality depends on the hardware’s specifications, on the other hand, stylus, especially the top diamond part, is also a key point at the same time.
As you can see in the left photo, we are able to create that sensitive part by ourselves.
We would say the edge radius will be 2 micron or 5 micron.
If you use a good stylus on your equipment, your capability will be widened.  Don’t you think so?

We got useful information for you. Now we have some stock of our knives as below. If you order any model(s), we will finish it(them) just 1 week. If you need a knife urgently or you have some budget that you have to consume at the end of fiscal year, it might be a good opportunity to get products without waiting time. If you have some demands, please let us know.

As you might know, every model is limited in number.
We provide those items on a “first-come-first-served basis.”
Means, they are subject to prior sales.
There is a possibility when you ask for a knife, it is already sold out.  Sorry in that case.

We started to produce a rough cutter again from many customers’ requests. As you might imagine, nobody uses a Polishmaster anymore for more than 10 years here in Japan. That’s why our business was also extinguished at the same time. Nevertheless, there are many engraving companies still making cylinders by Polishmaster in other countries.

If you are not satisfied with your current use of a rough cutter by its quality, price, delivery time or other reasons, why don’t you try our model one time?
It might be a good opportunity to compare different models.
In our case, we do a “secret method” on the finishing.
You will probably get more beautiful surface roughness and longevity at the same time.

As you might know, we moved our office from Yokohama to Tokyo last October. Syntek was established originally in Shinagawa, Tokyo in 1978. Our office and factory were there until 2008. Now we are right back where we started. We just made a short video introducing our company.

Once you watch it you will probably know what we are doing.If you have any questions, please contact us.Our factory is open from Monday to Friday.  If you have any opportunities to come to Tokyo, why don’t you visit us to see our processing lines? Luckily, we are close to Tokyo Haneda International Airport(HND).
You are always very welcome!

When you exchange the used(dull) burr cutter to the new one, sometimes it takes time to set it up. Especially if you try to arrange the right and left parallelism correctly, you may screw up again and again. The setting time depends on the skills of operators. We would say the approximate exchange time is between 15 minutes to 90 minutes.

Some people are OK to wait for the term, however some others are not acceptable if it takes more than 1 hour.
You cannot run the machine during that period as you might know.
That is the reason we developed this detachable burr cutter.
Once you use it, you just remove the blade part. You will never arrange the parallelism anymore.
We would say, the changing time is no more than 2 minutes.
If you would like to engrave more cylinders, why don’t you try this cutter?

If you need more information…

Are you satisfied with the current width of diamond knives? Especially if you prefer to use “ULTRA” for ultrathin sectioning, 4mm was the maximum so far. It seems this record was broken by a knife manufacturer such as 8mm ultra 45-degree. We were very surprised when we heard that news. This is a marvelous revolution in this ultra-knife field.

Someone says “Records are made to be broken.”  We totally agree with this message.
This is our turn, isn’t this?  Can we win this time?  Why not?
Syntek sets a new record for the above 8mm.
We will provide you 10mm Ultra: both 35-degree and 45-degree.
That’s more like it, isn’t it?
5mm, 6mm or 8mm Ultra? Needless to say, we do it!
In the meantime, this “10mm knife” is the build-to-order item.  Ask us the details.
