Working with any tools is pleasant when it is securely "sitting" in the hand.
Tools such as needle files are sold without handles and therefore it is not always convenient to work with them. I don’t feel like making pens for each file myself. I offer here such a way out. He radically solves this problem once and for all. To do this, we take the used carbon dioxide cans for siphons and airguns and use a thin round file to bore a punched hole exactly according to the diameter of the file handle
The hole must be such that the handle fits snugly into it.
If you have few spray cans, you can change the removable handle during operation. You can make several pens.
The most important thing is that if the hole is large, then the file will hang and work will be inconvenient. You will have to fill the handle with epoxy.
