A few weeks ago I bought the Quangsheng low angle block plane from Workshop Heaven and it's a seriously good plane. Last week I was at another shipyard to help out with a teak deck and one of the guys there has the Lie Nielsen block plane. We compared the two and came to the conclusion the Quangsheng is the better plane. Both are identical in size but the Quangsheng is a tad bit heavier. If I had to guess I'd say about 100 grams. This is because the Quangsheng has a body made from CR40 steel (Chrome Molybdenum tool steel) vs ductile iron for the Lie Nielsen. The advantage of CR40 over ductile iron is that CR40 is more corrosion resistant and stronger. It's a better all round choice for a plane imo. The Quangsheng also has a better adjuster. The adjuster wheel on the Lie Nielsen is quite small and close to the blade. Because it's so close to the blade it doesn't leave a whole lot of room for your fingers. The adjuster wheel on the Quangsheng is larger which provides more grip. The Quangsheng also uses a different adjuster. The blade has 10 slots and 2 of the slots engage two tabs on the adjuster. Because the blade has 10 slots you can have the adjuster wheel stick out more at the rear which makes setting the depth a lot easier. It also has a finer thread enabling a finer and more controlled depth setting. Finally, the 10 slots give you more useable blade length. I also like the T10 carbon steel blade on the Quangsheng more. A2 has a tendency to chip while carbon steel dulls gradually. Carbon steel also sharpens much faster and takes a keener edge. The only thing the Lie Nielsen has over the Quangsheng is the casting is a bit cleaner and the powder coat finish is of a better quality. However, these two things don't affect the performance in any way. So in the end it's down to the price. The Lie Nielsen costs about $180 and the Quangsheng is $88. Given this very large price difference I'm baffled why anyone would choose the Lie Nielsen over the Quangsheng.
