Hobbies come in all shapes and sizes. Some keep you active while others are more sedentary, such as crafting hobbies. If wielding power tools and fire are where your heart lies, then finding a way to combine the two would likely be the best option. While making a flame thrower would certainly be a fun way to pass the time, it would likely leave you in some legal trouble whether or not you mean it to.
If you still want to use tools and heat, this Walnut Hollow Woodburning Tool might be able to let you live out some of your more arson-related dreams, without injury to anyone but possibly you! This is a soldering tool that comes with a variety of tips that will let you make your mark in different shapes. It comes with 11 points in all, and uses a dial to adjust the temperature.
This will plug into any standard two-prong outlet, and has a temperature range of 0-950 degrees Fahrenheit. You’ll be able to work on everything from foam and paper to leather and soft plastics, and there are instructions for which color on the dial corresponds to which materials. You’ll be looking at spending $23.99 on this device, but if this is a leisure activity and you can create something from it, you can turn those dollars spent into items that can be sold.
