Your advantages:

1. Massive Sewing Capacity: It easily punches through heavy materials (up to 7/8 inch thick) such as saddle leather, nylon webbing, and bioplastic. 

2. Heavy Thread Capability: It accommodates extra-thick bonded nylon or polyester thread (sizes #69 up to #415), ensuring structurally strong, heavy-duty seams for items like holsters and harnesses. 

3. Compound Triple-Feed (Walking Foot): The feed dog, walking foot, and needle all move in unison. This eliminates shifting between layers and smoothly pulls through sticky, tough, or multi-layered materials.

4. Cylinder Arm Design: The 9-inch cylinder arm allows you to easily sew 3-dimensional, curved, or tubular items like bags, shoes, and saddles.

5. Extra High Foot Lift: The presser foot can lift up to 25mm (1116 inches), making it easy to position bulky or extremely thick materials under the needle.

 

6. Barrel Shuttle Hook: It uses an extra-large bobbin and barrel shuttle hook, which holds more thread than standard bobbins and vastly reduces the frequency of re-threading on large projects.

 

7. Precision Control: It typically comes equipped with Kinedyne low-speed, high-torque servo motor. This lets craftsmen stitch at an ultra-slow pace, offering the pinpoint control needed to turn tight corners or perform stitch-by-stitch work.

8. Versatility and Add-ons: While built as an absolute workhorse, the CB3500 can be adapted for smaller or flatter goods. It features over 20 available attachments (like flatbed attachments or specialty harness feet) that allow it to be used for projects ranging from custom knife sheaths to wallets and purses.

9. The "Short Arm" Savings: The CB3500 is identical to the flagship CB4500 but features a shorter (9-inch) cylinder arm. This makes the machine more affordable and compact, perfect if you focus on smaller, 3D items like knife sheaths, holsters, and belts.
