I found this question asked on this forum once before by another but no replies on that one. I am trying to identify one of my swivel knives it has HD inside a Diamond as it's Brand. Who makes it, are more available etc. Anything would help it is a pretty decent swivel knife

Thanks, I signed up for a class while at the thread store so hopefully that will help as well, "Leatherworker" I actually have a manual and have done an extensive search on the internet and couldn't find the answer maybe because they don't publish it or I don't know enough about what I am reading. For now I am going with Tex 90 and a 140 needle. Once I have gained some more knowledge about tensioning etc. I may go bigger on the top. Wallet guts and Biker Chaps / Vests are the heaviest it will see anyways.................Thanks for the help

Hello all very helpful site you have here, after reading here for a while I decided the Consew 206RB-5 fit my applications so I have one now. It has the servo motor and the flip up guide installed. I have a few questions please. 1. What is the heaviest thread that can be used? 2. Any do's and don'ts or modifications advise based on your experience? I should add I have always hand sewn so I know nothing about sewing machines this is square 1 for me so any advise is welcome and appriciated.
