I find that for the average person that does not have access to large Baldor buffers like I do. Try a Dremel tool with the muslin buffs on it and a little rouge on the buffs. This works very well on small localized rust spots. Then you can lightly blend the buffing out over the whole blade. You can achieve a very nice finish this way, with some time and effort. If the rust is deep enough that that does not work , there are allot of different abrasive attachments for the dremel tool. Some very coarse some soft as angelhair. Warning: watch out when using any power tool not to get the blade hot to the touch. If it is too hot to keep your hand on comfortablly, cool it with water. Never want to ruin a good temper or hardening, as the case may be. Good luck to you!
