⭐ Customer Reviews and Testimonials

Authentic User Feedback

🔧 Professional Tradesman Review

⭐⭐⭐⭐⭐ James Carter - Electrician
"I’ve used this GreatStar utility knife daily since I bought it in February 2025, and it’s become my go-to cutting tool on every job site. The lockback mechanism is rock solid—no accidental slips, even when cutting through conduit bundles. The 0.024in blade slices through electrical tape and plastic sheathing like butter. Best part? Swapping blades takes seconds thanks to the quick-change system. After five months of heavy use, the handle still feels secure and comfortable, even with gloves on."

Purchase Date: February 2025 | Usage Period: 5 months

✂️ DIY & Crafting Enthusiast Review

⭐⭐⭐⭐⭐ Emily Tran - Home Crafter
"I bought the Base Model in October 2024 for my scrapbooking and packaging projects, and I’m blown away by how precise it is. The ultra-thin blade lets me make clean, straight cuts on cardstock and adhesive vinyl without tearing. It folds up neatly and fits in my craft pouch—so much safer than my old box cutter. I love that it’s lightweight but doesn’t feel cheap. After eight months of weekend crafting, the blade still holds an edge, and replacement blades are easy to install."

Purchase Date: October 2024 | Usage Period: 8 months

🛠️ Construction Site Foreman Review

⭐⭐⭐⭐☆ Marcus Reed - Carpentry Supervisor
"We equipped our crew with the Advanced Model in January 2025, and overall, it’s been a solid performer. The reinforced lockback and high-carbon steel blades handle drywall, insulation, and plastic piping without issue. My guys appreciate the enhanced grip—it doesn’t slip even with sweaty hands. Only reason I’m giving four stars is that the manual retraction, while reliable, could be faster during rapid task switching. That said, durability and safety are top-notch. We’ve had zero injuries since switching from our old friction-lock knives."

Purchase Date: January 2025 | Usage Period: 6 months

🚒 Emergency Response Gear Review

⭐⭐⭐⭐⭐ Lieutenant Dana Perez - Fire & Rescue
"Our department tested the Pro Model in March 2025 for inclusion in our emergency kits, and it passed with flying colors. The auto-retract feature is a game-changer—quick access and instant blade retraction under stress. We used it to cut seatbelts and packaging in training drills, and the premium stainless steel blade (X50CrMoV15) showed no signs of corrosion after exposure to water and debris. Compact, rugged, and OSHA-compliant. Exactly what we need in high-pressure situations."

Purchase Date: March 2025 | Usage Period: 3 months

🎒 Outdoor Enthusiast Review

⭐⭐⭐⭐☆ Alex Nguyen - Backpacker & DIY Camper
"I toss this in my pack for trail repairs and campsite prep. Got the Base Model in November 2024, and it’s been perfect for slicing rope, opening packages, and light wood trimming. The 100g weight is negligible, and the foldable design means it doesn’t snag or pose a hazard. I’ve dropped it a few times—no damage, and the blade still locks securely. Only downside? I wish the handle had a lanyard hole, but otherwise, it’s a reliable, no-fuss tool for on-the-go use."
