How to identify a top quality razor?

	The quality of razors is mainly determined not by what they are made of, but by how they are made. Better (and more expensive) needle shavers aren't just cast, dyed, and then sold, they're machined to improve fit, performance, and ease of use.
	For the precise tasks required of a spoke razor, it is important that the parts fit together correctly. Some razor blades are inserted upside down, with the bevel up. While needle razors can be used in this way, downward bevels are generally preferred. You will also find that low quality razors are not smooth and the parts rub against each other, meaning they cannot work effectively. Another problem you may run into is that the blade is not sharp enough.
	These are problems that can be solved by replacing parts with better ones, machining and sharpening parts, or buying a better model first. For more information on sharpening and how wire razors work, see: How to sharpen a razor blade и Needle maintenance and care
	To determine a better model, look at the finish/paint of the tool and how well the pieces fit together. It should be pretty easy to see if the tool has been machined or not. Better quality tools will cost more due to the resources and time involved in making them.
