NEWBIE cutting nails/ staircase renovation - multitool generating sparks?

[BobTheLuLu]

Hi all! Hoping for some advice: I'm renovating our stairs which includes the removal of some nails. I've checked: not all need to be removed and the ones I'm currently removing will be replaced with screws from the step above into the riser below.

When I use my dewalt multitool with nail cutting blade, I sometimes generate sparks. Am I (ab)using the multitool incorrectly?

From what I've read it's common for power tools to generate some sparks, and I'm well protected with goggles, gloves, sleeves, etc. but I mainly want to make sure I'm not butchering my tools. And the online videos only showcase perfect scenario's with nice, clean nails, etc.

Thank you!

Yeah, don't worry about your tool, unless it's overheating. When you cut steel with power tools, the tiny fragments heat up and turn into bright sparks. Just don't have anything highly flammable nearby! I used to be a welder, so I know about sparks!
