Thanks for response to my previous request.
Followed each reply and still don't know how to make kHz tuning fork
(as an electronic component).
Queried Wikipedia for tuning fork.

by Meat Plow http://www.qth.com/inrad/ - crystals in MHz frequency band
avaliable only.

by Rich Grise http://www.fairchildsemi.com/ds/CD/CD4060BC.pdf - binary
counters

by Don Lancaster - Our lowest frequencies are 28.8 kHz, 108 kHz, 153.6
kHz, 250 kHz, 256
kHz, 307.2 kHz, 326.4 kHz plus hundreds of higher frequencies.

by whit.... For wristwatches, a tuning-fork is used, and one can
micromachine it .....
from quartz and laser-trim its weighted tines for frequency and couple
to it using
the quartz material's piezoelectric properties.
The typical resonators used for 5 kHz are tuning forks and guitar
strings, or they aren't mechanical at all...

clock oscillator only
The characteristics of the 32.768 kHz
model are presented in this data sheet.
Are data sheets for lower frequencies also avaliable ?

Catalog
Section D - Crystals and Oscillators
unfortunately, frequency range is MHz notr kHz
Quartz Crystals - ECS-31 Series is for kHz range p- lowest frequency is
32.000
32.768kHz Tuning Fork Crystals
lowest frequency offered non-programmable oscillator is for 20.000 kHz.

So is there no chance to make, order a non-programmable oscillator for
kHz band
5 kHz, 10 kHz or the like to test wireless energy transfer by Tesla ?

Mayby a small, home arranged lab could micromachine or laser-trim a
tuning fork to meet my needs or should I give up the idea of ordering
samples of tunning forks with frequenciec in kHz band of my interest.

It seems you need a clock source at 5kHz / 10kHz / whatever. Just get an
oscillator (or make your own with a crystal / tuning fork device /
resonator) and divide it down.

I don't see anything difficult about that.
