Edge Pro Apex 4 Knife Sharpening System

What types of knives can I sharpen with the Apex 4 system?

The system sharpens any blade up to 3.5" wide and any length. This includes chef's knives, paring knives, fillet knives, hunting knives, pocket knives and even serrated blades. The non-clamping guide system accommodates curved blades, tanto points and unusual shapes that other sharpeners cannot handle. The only limitation is blade width - anything over 3.5" won't fit through the guide.

How do I choose the correct sharpening angle for my knives?

Japanese knives typically use 15-degree angles per side for maximum sharpness. German and European knives work best at 20-21 degrees for durability. Hunting and outdoor knives benefit from 22-24 degrees for toughness. The system has clear markings at these common angles, but you can adjust anywhere between 10-24 degrees for custom requirements.

How long do the water stones last before replacement?

Water stones last considerably longer than oil stones because they don't become clogged with metal filings. With regular home use, expect stones to last 2-3 years. Heavy professional use may require replacement sooner. The stones are economically priced and easy to replace - simply twist the knob to remove the old stone and install the new one.

Can beginners use this system effectively?

Yes, the guided angle system eliminates the skill barrier of freehand sharpening. The instruction DVD and manual provide clear guidance. Most users achieve professional results immediately. The system prevents common mistakes like inconsistent angles or excessive pressure. Even complete beginners can create sharp, polished edges that surpass factory sharpness.

What's included in the complete Apex 4 kit?

The kit includes the Apex sharpening system, five water stones (120, 220, 400, 600, 1000 grit), polish tapes (2000 and 3000 grit), mounting blanks, 8" ceramic hone, instruction manual, DVD, cleaning cloth, water bottle and black Cordura carrying case. This represents everything needed for complete knife maintenance from dull to razor-sharp.

How does this compare to electric knife sharpeners?

Electric sharpeners remove excessive metal and create heat that damages blade temper. They often produce wavy, inconsistent edges. The Apex 4 removes minimal metal whilst creating perfectly straight, consistent edges. The water stones prevent heat buildup, preserving your knife's metallurgy. Results are superior and your knives last much longer.

Is the system truly portable for outdoor use?

Absolutely. The entire system weighs just 454g and fits in the included carrying case. Setup takes seconds on any flat surface - no power required. The water bottle provides the only liquid needed. This makes it perfect for hunting camps, fishing trips, or professional kitchens where maintaining sharp tools is critical.

How do I maintain and clean the sharpening system?

Maintenance is minimal - simply rinse stones with clean water after use and allow to air dry. The metal components wipe clean with the included cloth. Store in the carrying case to prevent damage. No oils, lubricants, or special cleaners required. The robust construction means the system will provide years of service with this basic care.
