Maintaining and Sharpening Your Ninja Stars

Okay, you’ve got your ninja star collection, you’ve learned how to throw them now what do you do to keep them in tip-top shape and maintain their edge.

Clean and Oil Your Throwing Stars

Unless you are a shuriken master you will invariably miss your target at some point and this often will leave dirt and grime on your stars.  Simply you can wipe them off with a towel lightly moistened with water or isopropyl alcohol.  Make sure to dry them completely as they are made of metal, stainless or not they could eventually rust.  Check the edges and if nicked or otherwise dulled you can go ahead and sharpen them with a stone (see below).  Otherwise, you can put a little 3 in 1 oil, WD-40, sewing machine oil, or another lubricant on them to keep them as good as new.  If you use an oil-based product just be sure and wipe them off before your next throwing session.  You don’t want your throwing stars slipping out of your hand and puncturing you, your brother, or any other living being.

Sharpen Throwing Stars

After some use your ninja stars are going to eventually dull.  Not to worry, with a little time and elbow grease you can get them back to their original state or even sharper depend on the star.  Do not under any circumstances use a grinder on your throwing stars!  You have been warned.  About 30-40 strokes at about a 20-25 degree angle with a sharpening stone will do the trick.  We recommend the quality whetstone kits listed below for sharpening your ninja stars.  There is a course stone to start your sharpening and a fine stone to hone it to a fine edge.

It’s relatively inexpensive and works great for a variety of weapons and knives you have lying around the house.  There are a lot of options out there and many of them will work just fine.  For most, a slight application of 3 and 1 oil will help in the process.  When finished with the sharpening stone clean your star as above and rinse off the sharpening stone as well and dry completely.
