S09 New Design Professional Fixed Angle Apex Knife Sharpener Review: Is It Worth the Hype?

We’ve all been there: you’re trying to slice a ripe tomato for a salad, and instead of a clean cut, your knife just squashes it. You find yourself sawing back and forth, getting frustrated, and realizing your kitchen blades have become basically useless.

Most people reach for those cheap pull-through sharpeners you see at the grocery store. They work for a week, and then they stop. If you’re tired of dull knives but don’t want to spend hundreds of dollars on professional sharpening services, you’ve probably stumbled across the S09 New Design Professional Fixed Angle Apex Knife Sharpener Kitchen Knife tools Knife Sharpening System with diamond stones Set.

I’ve been testing this system out to see if it actually delivers a razor-sharp edge or if it’s just another piece of kitchen clutter. Let’s get into the details.

What Exactly Is the S09 Sharpening System?

At its core, the S09 is a "fixed-angle" sharpening system. Unlike holding a stone in your hand and guessing the angle, this system locks your knife into place. You move the sharpening stone across the blade using a guide rod.

The main appeal here is precision. By keeping the angle consistent every single time, you get a much sharper, more durable edge than you could ever achieve by eye. It’s marketed as a budget-friendly alternative to high-end professional rigs like the Edge Pro or Wicked Edge. Plus, since many retailers offer free shipping on this model, it’s a very low-risk investment for someone looking to upgrade their home kitchen game.

Real-World Features That Actually Matter

When you pull this out of the box, you’ll notice it’s a bit of a "Lego set" for knives. Here is how the features translate to your daily life:

The Diamond Stone Set The kit comes with several diamond stones of varying grits. Diamond is great because it’s incredibly hard. It can handle even the toughest stainless steel or carbon steel knives without wearing down quickly.

Coarse stones: Use these to repair chips or set a new angle on a really dull knife.
Fine stones: These are for the "polishing" stage, where you turn a sharp edge into a scary-sharp one.

The Fixed Angle Mechanism This is the heart of the product. The rod allows you to set the exact degree of the edge. If you want a 20-degree angle for a sturdy chef’s knife or a 15-degree angle for a thin Japanese-style blade, you can lock it in. Because the angle is locked, you don't have to worry about human error. You won't accidentally round off the tip of your blade.

Sturdy Base The S09 usually comes with a base that keeps the unit from sliding around your counter. This is important because you’re dealing with sharp blades—the last thing you want is the sharpener sliding while you’re mid-stroke.

The Honest Pros and Cons

I believe in being straight with you. No product is perfect, and this system definitely has its trade-offs.

The Pros:

Consistent results: Once you learn the rhythm, every knife in your drawer will be equally sharp.
Versatility: You can sharpen almost anything, including pocket knives, kitchen cleavers, and even scissors.
Cost-effective: It’s a fraction of the price of "pro" systems while doing 90% of the same work.
Durable stones: Diamond stones last a long time compared to traditional water stones that can crack or dish out.

The Cons:

The learning curve: It isn’t "plug and play." You have to watch a video or read the instructions carefully to set it up correctly the first time.
Plastic parts: To keep it budget-friendly, some of the knobs and brackets are made of plastic. If you crank them too hard, they might crack. Treat it with a little care.
Setup time: You can’t just sharpen one knife in 30 seconds. You have to clamp the knife, set the angle, and swap the stones. It’s a bit of a project.

Who Is This For (And Who Should Skip It)?

This is for you if:

You own a nice set of kitchen knives and you’re tired of them feeling dull.
You enjoy the "DIY" process of taking care of your own gear.

You want a "quick fix" and you’re not willing to spend 15–20 minutes learning how to sharpen a knife properly.

You get frustrated easily by assembly-required tools.
