FOI request to Thames Valley Police re the knife found at Harrowdown Hill

Earlier today I asked the following questions of Thames Valley Police in a Freedom of Information request:

This is a Freedom of Information request.

1. Was the knife found at Harrowdown Hill shown to any member of the Kelly family? (I am aware that a photograph or photocopy was shown. I wish to know if any family member was shown the knife itself.)

2. Were there any features of the knife which allowed its positive identification as having belonged to Dr. David Kelly? If any such features were present, please list them.

3. What forensic tests were carried out to determine whether or not the knife was capable of producing the wounds in Dr. Kelly's left wrist?

4. Did the knife show evidence of having been sharpened?

5. Was the sharpness of the straight part of the edge sufficient to incise human skin?

6. Was the sharpness of the curved part of the edge sufficient to incise human skin?

7. Was a forensic expert consulted regarding whether the knife could have caused the wounds in Dr. Kelly's left wrist?

8. If so, who was the forensic expert?

9. Did the forensic expert provide a written report to Thames Valley Police? Or to the Hutton Inquiry?

10. What was the make and model of the knife found? Was the handle made of wood or metal?

Thank you
