Thank you sir for the kind words.
If you are wanting to sew sheaths definitely the Cobra 4. Many lighter machines will say they will sew say 7/16" or 1/2" thick and will use heavier thread but they won't, not well. I have never heard of anyone buying a Cobra 4 and wishing they hadn't. The after sale service is legendary and deservedly so. We have a Cobra 4 which I use on heavier items, sheaths, rifle scabbards, horse tack etc. We have a Cobra 18 for lighter work: wallets, belts, bags, chaps etc We also have a Cobra Np 4 Skiving machine which my wife uses often on her bags. Wants on our outfit? Cobra 26, a smaller cylinder arm machine. Sews about the same weights as the Cobra 18 but is a cylinder arm machine not a flatbed like the 18. Comes certain times on certain projects ya need a flatbed and other times a cylinder arm. Also on the want list but kinda on the back burner is a Cobra Class 14 splitter. We get around needing that for the most part by buying different weights of leather. Ya wanna look up Leather Machine Co.
Interesting story to relate about their legendary service. Resharpening the skiving machine is kinda complicated and they tell ya just call Vince when ya need too. I've done it enough now I don't need to call Vince anymore but awhile back it was time. I called and told Heather the gal that answers the phone I needed to talk to Vince. She says let me let ya talk to Dave (one of the owners) as Vince isn't in. Dave picks up and says Oh ya need to sharpen, yeah ya want Vince, he's home sick (with the rona), here's his personal cellphone number. What I'm not gonna call him at home if he's home sick! Oh go ahead, he'd probably enjoy the call. You don't pay him enough. Yeah I do. So I called Vince. Dang if he didn't talk me through it and we ended up talking for bout an hour, I think he might of been bored. Anyhoo fixed me up literally from his sickbed at home. If you gonna buy a leather machine get the Cobra and if you want to make sheaths, holsters, scabbards etc get the 4. They come in the Premium and Base packages and I got the base package myself. Haven't seen the need, at least how I work for a lot of the other do dads in the Premium package.
A few Cobra 4 projects:
Both Machines:
On this Rangeflap holster the water buffalo leather lining is sewn in using the 18 and then holster is sewn together using the 4.
Same on this Tote Bag. All stitching is done on the 18 except the final top stitch at the top of the bag, which is done on the 4:
Cobra 18:
Anyhoo , ya get the idea.
