I've never tried this device for tying knots although it does sound as if many others are impressed. I will add, however, that I have done a considerable amount of line testing on my own and only on occassion does the line break at the knot. Also, I cannot personally remember losing a fish in many, many, years as a result of a poor knot on my part. I did have a steelhead break the line this year (fireline) but it was at the reel, not at the knot. Hey, send me five bucks and I will tell you what knots I'm using, cough, cough. :--D
