I mod and repair Jerrold, General Instrument - DP5, DP7, DPV7, CFT, DCT, and DPBB model cable boxes. We call this tool a J-Tool, so I was hard pressed to find it called something else like a gamebit. Needless to say this tool or "J-Tool" works well when applying a little pressure to the Linehead 3 security screws on the cable box system zero security screw heads. If you are a modder like me and can't find this tool, then read my review because this is the tool needed to remove the special tamper screws on DP5 to CFT and DCT cable boxes.
