What makes this scissors knife stand out from other products is its durability and versatility?

That’s a great question, Chee Wei Chan! The Problue KN-77 Tiara Pro Knife is indeed known for its exceptional durability and versatility.

Amy Tan –
I was really impressed with the sharpness of the knife and the functionality of the scissor part, but the compact case is a bit too small for my liking.
Kwang Thye Tan –
The compact quick-release mechanism is so convenient to use. And the price is more than reasonable for the quality.

I must say, the serrations on this knife are a game-changer. The 3.5 inch blade is perfect for various tasks.

I’ve had this knife for a few months and it’s been my go-to for most of my kitchen tasks. Only downside is that it’s a bit pricey.
Jenny Lee –
However, the stainless steel might be prone to rusting after extended use, so make sure to clean it regularly.
Emily Low –
Can the Problue KN-77 Tiara Pro Knife be used in high-heat environments?
Junhao Lo –
Thank you for sharing your question about the Problue KN-77 Tiara Pro Knife, Emily. The product description doesn’t specifically mention its high-heat tolerance, but the materials used for the knife, 420 J2 stainless steel, are generally more resistant to corrosion and heat than other materials. However, we can’t guarantee its performance in extreme heat environments. For optimal performance, it’s best to avoid using the knife in areas with temperatures above 100°C (212°F).

Joan Lye –
The only thing I’m concerned about is that the material may scratch easily. Is there any way to prevent that?
Junhao Lo –
Thank you for sharing your concerns about the Problue KN-77 Tiara Pro Knife. We understand your worries about the material scratching easily. To prevent scratching, we recommend storing the knife in a dry place, away from direct sunlight. Additionally, applying a thin layer of food-grade wax or silicone lubricant to the blade can help reduce friction and prevent scratches. If you have any more questions or concerns, please don’t hesitate to ask. We’re here to help.

However, we can assure you that all the components of the knife, including the blade, are made of high-quality 420 J2 stainless steel. If you have any further questions or concerns, please don’t hesitate to ask.
Chelsea Wong –
Does anyone know if this knife can be sharpened further?
Junhao Lo –
Thank you for your question, Chelsea! The Problue KN-77 Tiara Pro Knife is made from 420 J2 stainless steel, which is a high-carbon stainless steel material known for its excellent edge retention and resistance to corrosion. Many of our customers have reported sharpening their knives successfully using sharpening stones or sharpening steels. However, we recommend consulting the user manual for specific guidance on sharpening, as the process may vary depending on the desired level of sharpness. If you have any further questions, feel free to ask!
Daniel Yeo –
How does this compare to a traditional sharp paring knife?
Imran Hanafiah –
Hi Daniel, thanks for reaching out about your question! The Problue KN-77 Tiara Pro Knife – Sharp Tip is designed to be a multi-functional tool with both a sharp tip blade and a pair of scissors. Compared to a traditional sharp paring knife, the Problue KN-77 Tiara Pro Knife offers a more compact and portable option. The serrations on the blade also make it suitable for tasks that require a more aggressive cutting motion. However, if you’re looking for a dedicated paring knife, a traditional paring knife might still be the better choice due to its precision and ease of use. It ultimately comes down to personal preference and the type of tasks you plan to use the knife for. If you have any more questions, feel free to reach out!
