Since the Jende Industries Guided Sharpener (JIGS for Knives) is designed with a dishwasher-safe philosophy in mind, it only made sense to pair it with a rugged, waterproof digital angle cube. We selected an IP65-rated angle cube that appeared to be the perfect companion for the system but rather than simply trust the specifications, we decided to put it to the test.
To verify its water resistance, we submerged the angle cube in a bucket of water and left it underwater for over a minute. After the test, the unit continued to function normally, proving that it could handle exposure to water without issue. The experiment was a success, and you can watch the full test in the video below.
Anyone who uses a guided sharpening system knows that water is part of the process. Sharpening stones are often soaked in buckets or basins, while waterstones, diamond plates, and lapping films are routinely sprayed to keep them performing at their best. As digital angle cubes have become an essential tool for achieving precise and repeatable sharpening angles, they inevitably spend a lot of time around water.
The Jende Industries Guided Sharpener (JIGS for Knives) was designed for use in a wide range of environments, from commercial kitchens and food processing facilities to outdoor workspaces, garages, and home workshops. In these settings, cleaning and sanitizing the workstation, exposure to moisture, and even unexpected rain are realistic scenarios. That makes durability and water resistance important considerations for any angle cube used alongside the system.
Our angle cube carries an IP65 rating, a recognized standard established by the International Electrotechnical Commission (IEC). Unlike the broad marketing term “waterproof,” an IP rating provides specific, independently tested levels of protection.
The first digit, 6, indicates complete protection against dust ingress. The device is considered dust-tight and fully protected from contact with airborne particles under controlled testing conditions.
The second digit, 5, signifies protection against low-pressure water jets from any direction. During testing, water is projected through a 6.3 mm nozzle at a rate of 12.5 liters per minute and a pressure of 30 kPa for a specified duration without causing harmful effects.
Of course, we wanted to take things a step further. Rather than simply relying on the official rating, we decided to perform a test that most users would never intentionally attempt: fully submerging the angle cube in water. While IP65 certification does not require submersion resistance, we were curious to see how it would perform under more extreme conditions.
The results speak for themselves. Watch the video below and see how the angle cube handled the challenge.
