Frequently Asked Questions
What is the blade length of the QSP Viper QS166-B1?
The QSP Viper QS166-B1 has a 4.00" (101mm) blade and measures 8.50" (215mm) overall, putting it in full-size outdoor fixed blade territory rather than pocket-knife territory.
Is 10Cr15MoV good knife steel?
10Cr15MoV is a stainless steel with a composition comparable to VG-10, giving the QSP Viper QS166-B1 good corrosion resistance, respectable edge retention, and easy resharpening. QSP hardens it to 59–61 HRC.
What is a clip point blade?
A clip point has the spine "clipped" back near the tip, creating a finer, more controllable point with a long cutting belly. On the QSP Viper QS166-B1 this makes it well suited to detail work, skinning, and general slicing.

Yes. The QSP Viper QS166-B1 includes a molded sheath weighing roughly 2.68oz (76g) for secure belt carry.
How do you sharpen the QSP Viper QS166-B1?

Is the QSP Viper QS166-B1 good for camping and bushcraft?
Yes. With 4.5mm blade stock, a full-size 4.50" handle, and a stainless blade, the QSP Viper QS166-B1 handles camp chores, food prep, feather sticks, and general outdoor utility work, and its stainless steel resists rust in wet conditions.
