Another demonstration that you chime in on everything... knowing nothing and with useless information.
A grinder with a cut off wheel for a ONE millimeter mild steel pin? My nail clippers could cut that!
Can he wait? For some Made in China PPOS ordered from Harbor Freight?
Harbor Freight is a US outfit. The cheapest shipping would cost more than the finest tool at Canadian Tire or any hardware store on every other street corner in Canada. Never mind customs brokerage!
I agree1 mm mild steel can be easily cut with a decent pair of diagonal side cutters found at Home Depot, Canadian Tire, any hardware store or Princess Auto
Heavier than that and you can go to a set of "mini" bolt cutters at Princess Auto
