I believe that I have been sewing leather before most of the members here were born. This is not a plug for sympathy but a God given fact!!! What ever that is worth!!! It is my opinion that any one that does enough leather work to warrant a stitcher should acquire one as soon as he/she can do so for a variety of reasons. It is a labor and time reducer that allows you to be more competive in the sales arena. It is less abusive to your hands. Unless you are very proficient in hand stitching (?) the machine stitch will be more consistent. Very few people can tell the difference between a well executed hand stitch and a machine stitch.
The craftsman that states the hand stitch is stronger than the machine stitch is speaking without knowledge of that fact in order to increase the stated value of the product he has produced in order to compensate for the increased time and labor involved------without producing a superior product. The fact is, that a comparable product, hand stitched or machine stitched is generally overkill and the strength of the stitch is not entered into the equation as STRONGLY advocated by the person with the sore paws. It stands to reason that the more economically you can produce an article, the more competively you can price it, which definitely gives the machine stitch an advantage. This situation is what causes the hand stitcher to tout his work as superior in order to compete at a higher level of compensation. Although I hesitate to state that the maker is prevaricating as stating facts is concerned---that is basically what is happening
Some of the best known, most superior in knowledge and skills in the leather crafting world, universally use machine stitchers to accomplish that which they do so remarkably well. If you can find fault with the fact that they have diverged from hand stitching (which they all know too well) to using that which science and industry has developed over many decades, show me the valid reasons that one might have come to those conclusions-----and I will be the first to back down on what I have written here.
FACT-----the finest articles produced from leather are usually machined stitched by professionals that will not revert to hand stitching unless the area can not be reached by the stitcher that they have at hand. The argument over the virtues of hand stitching over machine stitching is a fallacy perpetuated by the craftsman that does not produce enough to warrant the expense of the machine. Been there, done that----Sandy
