For anyone needing tungsten nail weights.
If you want more weight to the fluke or whatever. Buy a pack of these for $12 bucks. Fiber cut off wheel to cut them to length. Sharpened on a bench grinder. Grind a couple of notches in the side, if you feel they'll slip out the plastic. For which they won't.
Compare to a small pack of the Mustad Tungsten, 'Nail Weights' at $10.
(Edit to add: When you see these packs. They'll be different colors. You can use any color but Red. Known as 'Red Tungsten'. Don't buy it and definitely don't go cutting on it. The blue ones in the picture are 3/32". They sell bigger diameters and smaller.)
