LodeStar Pile Black Filing/Sanding Tools (5x180mm 5-Piece Set)

Pros: Cheap diamond coated files. Very good where you need to grind something very hard by hand, for example fine tuning things made from glass or tungsten carbide.

Cons: A little rougher than i would have liked, especially if it's going to be used to sharpen something.

The coating of diamond dust should have been made all the way up to the top of the file shape.

Other: At this price, these are fantastic diamond coated files, just keep in mind that they will not last forever, especially if you do not wet-grind.

Pros: Just a pack of cheap files. Nothing more. Works fine for their price. Diamonds are ideal for grinding hard objects such as glass or hardened steel.

Cons: Not too comfortable to use, quite rough design, may be too thin handle.
Not sure. that the plastic handles can withstand the heavy load. so you should treat them carefully, without applying excessive force.

Other: Cheap. Good. No more or less.

Pros: The piles comes in a good storage bag. The piles are reader small so its impotent how you store them they will easy go missing. The diamond coting seems to be of good quality.

Cons: No real cons so far maybe the price is a bit high for Deal Extreme. If the coting seems ruff i am pretty shore thy will come down pretty quick.

Other: Good Stuff all around.
