It is used for adjustment of semi-fixed VR, trimmer condenser. I used it before, but the base part of the ceramic was broken, so I bought it newly. As this is a high frequency adjustment, this driver is indispensable.

The one of 1.7 mm used for 20 years finally broke (the cutting edge was OK), and at the same time those with large blade widths were also available. Although I had the opportunity to use various adjustment drivers variously in the active era, it was what I got used to and was back to 9000 which was dirty. I am glad that I was still able to get it. Generally it will be OK if there is one 2.6 mm.
