I like them but i always eat the flint up with my Vic. Tinker small blade, the flint is HALF buried into the mag bar. i have had to pry out 6!!! flints!! well, if anyone has a good striker, i need one, i have used the hack saw blades and do not like the spark output and the amount of damage it does to the bar. I do not want to pay $5 S&H for a $1 striker. Thanks ETS!
Try the Corona sharpener. You can probably find it in your local hardware store. It can serve as a multi use item and throws the biggest shower of sparks of any striker I have tried.
