How Each Clipper Type Works
The two main dog nail clipper designs—guillotine and scissor—cut the nail differently. A guillotine clipper has a hole where you insert the nail; a blade slides across to make the cut. A scissor clipper works like standard scissors: you place the nail between two blades and squeeze.
The BUSTER Nail Clippers are a scissor-style tool. They come in three sizes (Small, Large, Heavy Duty) and use a precision cutting blade to deliver clean cuts. The KRUUSE Guillotine Nail Cutter Economy Model uses a guillotine mechanism for a controlled action. Both are designed for safe, accurate trimming, but the feel and technique differ.

When to Choose a Scissor Clipper (BUSTER)
Scissor clippers like the BUSTER Nail Clippers give you direct visual control over the cut. You can see both blades and the nail tip as you squeeze. This design works well for dogs with thicker nails because the scissor action provides leverage without requiring you to push the nail into a hole.
The BUSTER line offers three sizes, so you can pick the right one for your pet. The ergonomic handle and stainless steel blades help reduce the risk of splintering or crushing. If you groom multiple dogs of different sizes, having the Small, Large, and Heavy Duty options on hand covers most needs.
When to Choose a Guillotine Clipper (KRUUSE)
Guillotine clippers like the KRUUSE Guillotine Nail Cutter Economy Model are often preferred for small to medium dogs and cats. The hole guides the nail into position, which can be helpful if your pet wiggles during trimming. The blade slides across the top of the nail, creating a clean cut.
This model is compact (12.5 cm) and nickel-plated for corrosion resistance. It is an economy model, so it focuses on essential functionality at an affordable price. If you trim nails occasionally and want a simple, one-size tool, this is a practical choice.
What the Supplied Information Does Not Cover
The catalog does not provide operating instructions for either clipper. General safe trimming practices (avoiding the quick, using styptic powder) are not confirmed by these product records. Always consult your veterinarian or a professional groomer for technique guidance.
Neither product record specifies nail thickness limits or recommended frequency of use. For the KRUUSE guillotine model, the catalog does not state whether replacement blades are available. For the BUSTER clippers, the catalog confirms three sizes but does not list the exact blade gap or handle dimensions for each variant.
