Without Drawing, Sample Is Ok

Weeks ago, a new customer asked about pelletizer knife, they have picture of pelletizer knife, but no detailed drawing, for this pelletizer knife inquiry, we could quote to them, but not able to make sample. If you meet the similar situation, best solution, is to send us a sample, and we make according to the sample. It saves a lot of time and won't make mistake. But if you have any better idea, let's discuss together.
