I’ve been using this Problue knife for months now and it’s still holding up well! But I just wanted to know how it performs in very cold water? Will the blade will be sharp as usual?

Thank you for sharing your experience with the Problue KN-73 420 Stainless Steel J2 Sharp Tip Style. We’re glad to hear it’s been performing well for you. As for your question, the knife is designed with a durable 420 J2 stainless steel blade that maintains its sharpness under various conditions, including colder waters. However, it’s worth noting that the sharpness of the blade may decrease if it gets submerged in saltwater for extended periods. To maintain the blade’s sharpness, we recommend frequent cleaning and proper storage. Would you like to know more about caring for your Problue knife?

Love the look of the knife!! Is there any option to buy the knife separately without the sheath or rubber leg straps?

Unfortunately, we don’t currently offer separate purchases for the knife without the sheath or rubber leg straps, as they are considered essential components of the product. However, we’ll note your feedback and review our options for future product configurations.

Love the use of high-quality materials and the ergonomic grip of the knife feels extremely comfortable in my hand. Also great for the long-term durability and strength of knife it gives. one minor issue is I felt a slight dip in performance after first use but overall still happy with speed.

Overall satisfied with the product’s sharpness and feel of good quality. Can i simply ask what more qualities does the KN-73 have compared to previous model Problue-70?

Thank you for taking the time to share your experience with the Problue KN-73 420 Stainless Steel J2 Sharp Tip Style knife! We’re glad you’re satisfied with its sharpness and feel of good quality.
Regarding your question about the additional qualities of the KN-73 compared to the Problue-70, we’d like to highlight a few key differences. The KN-73 features a compact quick-release button that allows for easy one-handed operation, whereas some customers have reported difficulty with this feature on the Problue-70. Additionally, the KN-73 boasts a slightly smaller length of 4.55 inches (11.6 cm) compared to the Problue-70, making it more suitable for spear-fishing in tighter spaces. Please note that some details may be similar between models, but these specific features aim to enhance the user experience with the KN-73.

This Problue knife is a beast for spear-fishing, the sharp knife can cut through fishes in no time and it’s super lightweight with sharp tip design makes it perfect for underwater use. One thing I dislike about it is it doesn’t come with a cleaning cloth.

This knife is everything I wanted it to be! Yet i’m really curious about it’s maintenance cleaning what all products used?

Thank you for your wonderful review of our Problue KN-73 420 Stainless Steel J2 Sharp Tip Style knife! Congratulations on choosing the perfect knife for your spear-fishing adventures. For maintenance and cleaning, we recommend using a soft cloth and mild soap on the blade. You can also use a stainless steel cleaner to restore its shine. Be sure to avoid harsh chemicals or abrasive materials that may damage the blade. To clean the sheath, you can use a damp cloth and mild soap. The rubber leg straps can be wiped down with a dry cloth. Regularly cleaning and maintaining your knife will keep it in excellent condition. Please refer to our product manual for more detailed instructions.
