To the untrained eye, today’s product comparison may seem silly. Both of our featured products, the DX330 knife and the Rapid Response 3.90 knife, feature smooth blade-assist opening technology, and both are constructed with high-quality stainless steel and handle materials. However, for those who rely on knives in their work, or while hunting, the details about each knife, as outlined below, really do matter. For instance, rescue personnel who are constantly in motion while on the job will appreciate the DX330’s deep-carry pocket clip, which will keep the blade securely in one’s pocket. Read on to discover the differences between these two knives.

Overall, the DX330 may be the better choice for rescue workers, as it includes tools to break open car windows and cut away safety belts. On the other hand, the Rapid Response 3.90 may be the preference of hunters and knife aficionados, as it was created by legendary knife designer Ron Lake for smooth, safe operation, even in less-than-ideal conditions.
