Sharpening a pocket knife with a whetstone requires a systematic approach and some basic techniques. Here is a general step-by-step guide to help you:

1. Prepare the Whetstone: Soak the whetstone in water for about 10 to 15 minutes to ensure proper lubrication during the sharpening process. Follow the manufacturer's instructions if any specific soaking time is recommended.
2. Set up the Angle: Determine the sharpening angle for your pocket knife. Most pocket knives have a bevel angle between 15 to 30 degrees. You can use an angle guide or estimate the angle based on the existing bevel.
3. Hold the Knife: Hold the pocket knife firmly with one hand, ensuring a secure grip. Maintain a consistent angle between the blade and the whetstone throughout the process.
4. Start with the Coarse Side: Place the knife's edge against the coarse side of the whetstone. Move the blade back and forth along the entire length of the stone, maintaining the chosen angle. Apply light pressure and use long, sweeping motions. Repeat this process for several strokes, ensuring you sharpen both sides of the blade equally.
5. Transition to the Fine Side: Once you have established a decent edge on the coarse side, flip the whetstone to the fine side. Repeat the sharpening process, using the same angle and strokes as before. The fine side of the whetstone helps refine the edge and remove any burrs created during the coarse sharpening.
6. Test for Sharpness: After sharpening, carefully wipe off any metal particles or residue from the blade. Test the knife's sharpness by gently running it across a piece of paper or trying it on a small task. If the knife still feels dull, you may need to repeat the sharpening process or focus on specific sections that require further attention.

Remember to take your time and maintain a steady hand during the sharpening process. Regular practice will improve your technique and help you achieve better results. If you're unsure or uncomfortable sharpening your pocket knife yourself, it's always a good idea to seek guidance from an experienced individual or professional sharpener.
