Every job has it small secrets and cutting metal by jigsaw this task has it own.
In 1996 I got my Metabo St 450 from a friend, used but working, I was inexperienced about jigsaw (fine cut) back then, and over the years no one offered to me any special seminar about how much my work this would be improved if this tool was have speed control.
I was have to wait up to 2017, so to discover that there is similar model to my own well trusted Metabo St 450, which this has a magic
E letter over it.
The all story started when I discovered that my Metabo St 450 this has heavily damaged roller (blade guide) and nowadays there is no such spare part availability.
Then I thought to find an identical used tool getting it for spare parts.
By searching eBay I did engaged in one opportunity sale, this is about Metabo St
E 350, by translating in Greek language this speed control plate I did become wiser.
Lesson No1: Single speed jigsaw this is good only for woods.
Lesson No2: Metal and aluminum requiring about half speed than cutting wood.
Lesson No3: If you have old times professional power tools then try to get a used one for spare parts.
While I got this Metabo jigsaw St E 350 at 12E with 16E shipping from Germany, price of new spare parts even if they was available this would be higher ( roller guide & possibly a pair of fresh carbon brush).
