Back in the 60's, market stalls sold cheap far eastern tools that were useless, but these days in my experience most Far East stuff is adequate. To make up my last Screwfix order they had a cheap toolbox with some basic tools on offer (to be left somewhere which isn't particularly secure, so I didn't want good stuff). Most of them are fine particularly for the price, but today I used the junior hacksaw, and after about six strokes on a bit of studding it didn't have any teeth left.
On investigation, the blade was dead soft so I wondered charitably if it had missed the heat treatment. No: quench from red heat, and it's still soft, obviously mild steel! So someone is actually making fake junior hacksaw blades, blued to look just like the real thing. I find it quite surprising that there is a market for them.
