The JET 6" x 48" Belt and 12" Disc Sander (Model JSG-6DCK) offers a comprehensive set of features ideal for knife-making and other sanding tasks. It comes with a sizable belt size of 6 inches by 48 inches, allowing for ample surface area to work on larger pieces of material. The motor power of 1-1/2 HP ensures robust performance, capable of handling heavy-duty sanding jobs without faltering. A key benefit is the dual thumbscrew belt tracking adjustment, which helps keep the belt aligned during use, critical for precision work like knife sharpening.

The machine also includes a graphite-covered steel platen that runs cooler, prolonging the life of both the machine and the sanding belt. This sander excels in build quality, featuring a heavy-duty steel open-style stand that provides solid support, and precision-ground cast iron tables that can be adjusted for different sanding angles. Ease of use is enhanced by the push-button start switch that accepts a safety padlock for added security.

However, at 229 pounds, the sander is quite heavy, making it less portable. Additionally, while it does have a speed of 1725 RPM, it lacks variable speed control, which might be a limitation for those needing different speeds for various tasks. The warranty is decent, offering a 5-year cover, though this drops to 2 years for commercial or industrial use. Although not the most modern model, it remains a reliable choice for serious knife makers and woodworkers.

The WEN Benchtop Belt and Disc Sander (6502T) is a versatile tool with both a 4-by-36 inch belt and a 6-inch disc, making it suitable for various sanding tasks. For knife sharpening, the adjustable belt, which tilts from 0 to 90 degrees, is particularly beneficial as it allows precise control over the angle of sanding. The sturdy cast iron base is a major plus, as it minimizes vibrations, ensuring stable operation which is crucial for detailed work like knife sharpening.

The 4.3 Amp motor provides sufficient power with up to 3600 RPM, offering robust performance for both coarse and fine sanding tasks. Belt tracking may require some manual adjustment, but the presence of a tension release lever simplifies the process of changing sandpaper grits, enhancing ease of use. Build quality is solid, with the heavy-duty base contributing to its durability.

The machine might be slightly bulky and heavy at 37.1 pounds, making portability a bit challenging. Another potential drawback is the fixed voltage of 120 volts, which might limit usage in regions with different electrical standards. For users primarily interested in knife sharpening, the WEN 6502T provides reliable performance and solid construction, making it a worthy consideration.

The JET Variable Speed 8" Grinder and 4" x 36" Belt Sander (Model IBGB-436VS) is a robust and versatile tool suitable for those needing a durable and efficient belt sander for knives.

The 1 HP motor provides ample power, and the machine's variable speed control, equipped with a digital readout, allows for precise speed adjustments up to a maximum of 3600 RPM, which is crucial for knife sharpening tasks that require different speed settings based on the material being worked on.

The belt size of 4" x 36" is standard and sufficient for various sharpening needs, while the large spark guard eye shields enhance safety during operation. Additionally, the rubber-sealed bearings ensure maintenance-free sanding and prolonged machine life with pre-lubricated ball bearings that prevent wear and tear. Ease of use is supported by the included components such as spark guards, tool rests, and the sanding belt itself.

The machine's weight of 74 pounds might make it challenging to move around easily, and it may not be ideal for those with limited space due to its dimensions of 23.22"L x 12.22"W x 20.75"H. It is corded electric with a voltage requirement of 115V, which should be compatible with standard outlets. This product would benefit users who require a sturdy and efficient belt sander for regular, heavy-duty knife sharpening tasks.
