For those of you who cannot wait for a flat frog gig, Danielson Company, Inc. makes a four prong frog spear head that sells for $2.79. The socket is one inch outside diameter and it’s demensions are five and one quarter inches long by one and five eights inches wide. I bought two today at my local BiMart sporting goods store on sale for $1.95 each. Danielson is located in Auburn, Washington 98001-1707.
